Question

Justin can run 13.1 miles in 2 hours and 3 minutes. At that rate, how many minutes should it take him to run 20 miles? round to the nearest tenth.​

Answer 1

`187.8\ minutes`

Explanation:

step 1

Convert the time in minutes

`2h\ 3min=2*60+3=123\ min`

step 2

By proportion

`(123)/(13.1)(minutes)/(miles)=(x)/(20)(minutes)/(miles)\\ \\x=123*20/13.1\\ \\x=187.8\ minutes`
