Before turning in your walking and running worksheet, answer the following questions:
1) According to your worksheet, approximately how long (in minutes) would it take you to walk 1 kilometer? Do you believe this is true? Why or why not?
2) Approximately how long (in minutes) would it take you to run 1 kilometer? Do you believe this is true? Why or why not?
3) As you see, setting up proportions can help us solve so many different types of problems by setting smaller ratios equal to larger ones. But what about Question #7? Without comparing your ratios with other groups, do you think there will be a correlation between walk times and leg length measurements? If so, what do you think the correlation is? If not, why do you think there isn't one?

1) In an accordance with my worksheet, it will take approximately 9.75 minutes, or 9 minutes and 45 seconds for me to walk a kilometer.
ReplyDeleteI definitely think that this anticipation will turn out to be true, because I can keep the pace I am walking without getting too exhausted while walking 1 kilometer.
2) It will approximately take me 3 minutes and 12 seconds to run 1 kilometer. However, I think this guess is false and nonsensical, because I cannot continually run in the same pace.
3) I think there will be a relationship between walk times and leg length measurements, although not greatly. The correlation will be that these two factors will be inversely proportional, meaning that as leg length gets bigger the walk times will be reduced. Although you might be tall, if you lack stamina and pace than shorter people, you will run slower. However, since walking does not require much of the stamina and pace, the ones with longer legs will naturally go ahead quickly.
1. It will take me 11 minutes to walk 1 kilometers. I don't belive this because my walking rate might get faster or slower as I walk. It might not be exact, but 11 minutes might be around the time I walk 1 kilometers.
ReplyDelete2. It will take me 5.42 minutes to run 1 km. I do not believe this because by the end of running 1 km, I will get exhausted and start to run like a snail. Just like walking,my rate will become different as I run.
3. I dont think that you need to compare ratios with other groups in order to know a correlation becase there isn't one! There are many great runners and fast walkers that have short legs but they are very fast. There are also people with very long legs but they are very slow!There is NO correlation
1. It will take approximately 16.16 minute to walk 1km. I believe this is true because it takes about 20 minutes to walk 1 km. If I walk a little faster, I believe I can walk 1km in 16.16 minute.
ReplyDelete2. It would take 3.16 minute to run 1km. I don't think it is true because it will make me exhausted to run 1km in 3 minutes.
3. I believe there is a correlation between times and leg length measurements. If you have longer legs, you can walk farther in one step compared to people who have shorter legs. Therefore, unless people with short legs walk at a higher speed, people with long legs can walk faster than people with short legs at a same rate.
1. It will take approximately 10.5 minutes to walk 1km. When I am walking, I don't slow down or speed up so walking 1km in 10.5 minutes can be true.
ReplyDelete2. It will take approximately 4.4 minutes to run 1km. When I am running, I would definitely get tired and slow down. It is ridiculous to run in a same pace so running 1km in 4.4 minutes can not be true.
3. People who are taller have a greater chance to be faster. So I think there is a correlation between walk times and leg length measurements . However, there athletes who are tall but slow. Also, there are other athletes who are short but fast.
1) According to my worksheet, it will take approximately 11 minutes to walk 1 kilometer. I suppose I can walk 1 kilometer in 11 minutes because I will be able to keep the same pace without stopping. Therefore, I can assume that I could walk 1 kilometer in 11 minutes.
ReplyDelete2) It will take about 5 minutes to run 1 kilometer. I believe this is not true because while running, I don't think I can keep the same pace due to the exhaustion and the tiredness.
3) Yes, I think there is a correlation between walk times and leg length measurements. The correlation is that the longer your legs are the faster rate you will get. This is because if your legs are long, you can take bigger steps in shorter time than short legs with smaller steps. But this does not count on everyone; people with long legs might be slower than shorter leg people. Therefore, I think the correlation between time and leg length is that the shorer your legs, the slower the rate (for only some people).
It will take about 10 minutes and 88 seconds to walk a kilometer.i can be true depending on wether i stop in the middle or not.
ReplyDeleteIt will take about 3 minutes and 35 seconds to run a kilometer. I don't think that i can run a kilometer without stopping .
I think not doing #7 is fine because everyone has different leg length and if you have a longer leg than others than you can run or walk faster than one with the shorter leg. So there is a correlation.
It will take about 580 seconds, or about 9 minutes 40 seconds. But this is not true because my body will get tired after walking a lot.
ReplyDeleteIt will take about 200 seconds, or 3 minutes 20 seconds. Probably not true, because I will get exhausted and slow down.
Yes, I think there is because the longer legs you have, the longer length you can move within fewer steps.
1. I think it's reasonable to walk 1 kilometers in 11 minutes 15 seconds. This is because walking doesn't tire me out and I think if I continue walking at the same speed, I can finish.
ReplyDelete2. It would approximately take 4 minutes and 25 seconds to run 1 kilometer. I don't think it's true because you can get tired easily after a while and start slowing down.
3. I think there is a correlation between having longer leg length and a faster speed. This is because you can take longer strides with each step and that shortens the time you need to cover the distance.
1) According to your worksheet, approximately how long (in minutes) would it take you to walk 1 kilometer? Do you believe this is true? Why or why not?
ReplyDeleteIt would take me about 565 seconds or 9 min. and about 41 seconds. No, because walking for 1 kilometer at the same pace wouldn't be possible for a middle schooler. I would probably stop in the middle for a rest and so on, so it would be diffucult for me to go all the way without taking a rest.
2) Approximately how long (in minutes) would it take you to run 1 kilometer? Do you believe this is true? Why or why not?
It would take me about 250 seconds or 4 minutes and 16 seconds. Again, no, because It would be impossible for me to run to a long distance while keeping same pace. It will be harder than walking one kilometer.
3) As you see, setting up proportions can help us solve so many different types of problems by setting smaller ratios equal to larger ones. But what about Question #7? Without comparing your ratios with other groups, do you think there will be a correlation between walk times and leg length measurements? If so, what do you think the correlation is? If not, why do you think there isn't one?
I guess that if you have longer legs you could take bigger steps and arrive at your destination faster than people with shorter legs. So there is a correlation.
1. According to my worksheet, it would take me about 13.44 minutes. However, I don't believe it would be true if I actually did walk one kilometer. After all, I might be all restless and get a little faster and slower.
ReplyDelete2. Approximately, 3.83 to run one kilometer. For this one, too, I think that it isn't true. Everyone would get tired running one kilometer. So, I would get tired and slow down a lot of times, which would take some time for me to catch my breath.
3. I do think that there is a correlation between walk times and your leg measurment because people with longer legs take longer strides than people who have shorter legs. So basically, people with longer legs would take longer strides and take less time than people with shorter legs.
1. It would approximately take 9.5 minutes to walk one kilometer according to the worksheet. I don't believe this is true because as you walk, you will get tired and your speed will decrease. Then, it will take more time to walk 1 kilometer.
ReplyDelete2. It would approximately take 4.2 minutes to run one kilometer according to the worksheet. I don't believe this is true for the same reason as above. ( You can't run 1 kilometer in a same speed for the whole time.)
3. No, I can't find ant correlation between walk times and leg length without comparing with other groups. You have to compare different leg lengths in order to find correlation between them.
1. According to my worksheet, it will take me 11 minutes and 25 seconds. I believe that this will turn out true because unlike running because I am able to walk in a same pace constantly without getting tired.
ReplyDelete2. It would take me approximately about 5.34 minutes which would be 5 minutes and 34 seconds. I don't think this will appear to be true since I am not able to run constantly for a kilometer. At some point, I will have no energy left to run, so my pace would get slower and I would eventually stop.
3. Yes, I think it is clear that there is a correlation. If one's leg length is longer, the walk time would decrease because that person would be able to walk faster with longer steps. However, if one's leg length is shorter, the walk time would increase since that one's each walk step is shorter. In conclusion, if the leg length increases, the walk time decreases and vice versa.
Before turning in your walking and running worksheet, answer the following questions:
ReplyDelete1) According to your worksheet, approximately how long (in minutes) would it take you to walk 1 kilometer? Do you believe this is true? Why or why not?
- From what i got it would take me 9 minutes and 75 seconds to walk a kilometer.I do not think that is real because I am not such a good walker and will get tired, and propably faint if i walk that fast.
2) Approximately how long (in minutes) would it take you to run 1 kilometer? Do you believe this is true? Why or why not?
- From my worksheet i got 3 minutes and 92 seconds. I do not believe this is correct because like i said i am not a good runner.
3) As you see, setting up proportions can help us solve so many different types of problems by setting smaller ratios equal to larger ones. But what about Question #7? Without comparing your ratios with other groups, do you think there will be a correlation between walk times and leg length measurements? If so, what do you think the correlation is? If not, why do you think there isn't one?
- I think there will not be any difference because Jae Hyuns times are similar to mine ,but he has longer legs.. ^o^
1. it would take me about 8 through 9 minutes to walk a kilometer according to my wkst. However, i don't believe this because i would end up slowing up my speed rate because of exhaustion.
ReplyDelete2. it would take me about 4 through 4.5 minutes to run a kilometer according to my wkst. However, i don't believe this because it would be tired of running, causing me to slow down and rest for few minutes.
3. I think there is a correlation between walk times and the leg length measurements. I think the correlation is that if your leg length is long, then the walk time decreases since the amount of space you walk in one time would be higher than the shorter legs. (no offense to the short-leg people)
1. I would take me about 10 minutes to walk a kilometer. I don't believe that it is true because we are just predicting. When we really experiment it, it would have a different result because I might walk in a different speed or decrease in speed while i walk.
ReplyDelete2. It would take me about 4min and 10sec to run a kilometer. I also don't believe that this is true because like i said fore #1, I can decrease in speed while i run and I might run in a different speed. If I run in the same speed, this result might be true but I don't know how fast i ran.
3. I think there is going to be a correlation because all humans have different leg lengths. Some people have long, some have short, and some have medium sized legs. Also, the speed they all walk is also different. These two variable effect the results.
1. It would take me 12min 5sec to walk 1km. I don't think this is true because maybe there might be some variables. Maybe I could stop walking and rest for a few minutes or maybe I could slow down because I was getting a phone call of talking with friends.
ReplyDelete2. It would take me 3min 15sec to run 1km. I don't think this is true because I might fall down and stop for a few seconds and run again or I could slow down because I was tired.
3.I think there is correlation because of the difference of the lenght of the legs. But some people walk faster than people that have long legs.(maybe,..) anyways these problems might effect the result of this activity.
1) According to your worksheet, approximately how long (in minutes) would it take you to walk 1 kilometer? Do you believe this is true? Why or why not?
ReplyDeleteIt would take me about 660 sec.(11 min.) to walk a kilometer. I think this is false because It's hard to maintain a steady pace for a kilometer.
2) Approximately how long (in minutes) would it take you to run 1 kilometer? Do you believe this is true? Why or why not?
It would take me about 225 sec.(3-4 min.) to run a kilometer. I think this is false because that means I would have to sprint the whole kilometer, which would cause me to slow down in the end because I would be tired.
3) As you see, setting up proportions can help us solve so many different types of problems by setting smaller ratios equal to larger ones. But what about Question #7? Without comparing your ratios with other groups, do you think there will be a correlation between walk times and leg length measurements? If so, what do you think the correlation is? If not, why do you think there isn't one?
Yes, I think there is a correlation because the longer your leg is, the bigger steps you can take. Take Jae Hyun for example. He is very tall and he was the fastest in our class.
