Question

If a marathon runner averages 9.39 mi/h, how long does it take him or her to run a 26.22-mi marathon? Express your answers in h, min and s.

Answer 1

`t=2.8h`

`t=10080s`

`t=168 min`

Step-by-step explanation:

From this exercise we have velocity and distance. Using the following formula, we can calculate time:

`v=(d)/(t)`

Solving for t

`t=(d)/(v)=(26.22mi)/(9.39mi/h) =2.8h`

`t=2.8h*(3600s)/(1h) =10080s`

`t=2.8h*(60min)/(1h) =168min`
