Question

So I was confused on my test, the question was, The track coaches wanted to pick the fastest girl on the team for the big race. Addison ran 2 kilometers in 20 minutes. And Emma ran 5 kilometers in 1 hour. Who should the coaches pick? I picked Addison is that right?

Answer 1

Answer:

First you want to find the unit rate of each girl. But before doing that, you must convert one hour to minutes. There is 60 minutes in one hour. So

Addison runs 2 kilometers in 20 minutes, while Emma runs 5 kilometers in 60 minutes. We need to divide minutes by kilometers to find out how long it takes for them to run one kilometer.

Thus...

Addison:

20 divide 2 is 10. So Addison takes 10 minutes to run one mile.

Emma:

60 divided by 5 is 12. So Emma takes 12 minutes to run one mile.

Since the track coach wants to pick the fastest girl, Addison shall be the right option.

Have a good day!~
