Question

It takes Beth 157.2 minutes to run a 13.1 mile race. If she runs at a constant pace for the entire race, how many minutes does it take her to run each mile? *

Answer 1

Answer: It takes 12 minutes to run each mile.

Explanation:

Given: It takes Beth 157.2 minutes to run a 13.1 mile race.

i.e. Time taken to run 13.1 miles = 157.2 minutes

Then, Time taken to run 1 mile =
`\frac{\text{Time taken to run 13.1 miles }}{13.1}`

`(157.2)/(13.1)\\\\=(1572)/(131)\\\\=12\text{ minutes}`

Hence, it takes 12 minutes to run each mile.
