Question

If a marathon runner averages 8.83 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=2.97h

t= 10692s

t= 178.2 min

Step-by-step explanation:

We propose the following ratio:

`(t)/(26.22mi) =(1h)/(8.83mi)`

`t=(1h*26.22mi)/(8.883mi)`

t=2.97h

Equivalences

1h=3600s

1h=60 min

Calculation of t in minutes (min) and seconds(s):

t=2.97h*3600s/h= 10692s

t=2.97h*60min/h= 178.2 min
