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.

Respuesta :

Answer:

t=2.97h

t= 10692s

t= 178.2 min

Explanation:

We propose the following ratio:

[tex]\frac{t}{26.22mi} =\frac{1h}{8.83mi}[/tex]

[tex]t=\frac{1h*26.22mi}{8.883mi}[/tex]

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
