Answer:

The speed of marathon is 20.038 mile per hours

Step-by-step explanation:

Given as :

The distance of marathon = 26.2 miles

The time recorded for marathon = 1 hour 18 minutes and 27 seconds

So, The  total time = [tex]( 1 + \frac{18}{60}+\frac{27}{3600})hours[/tex]

Or , Total time  = 1.3075 hours

Let The speed in marathon = x mph

So, Distance = Speed × Time

Or,  26.2 miles = x × 1.3075

Or,   x = [tex]\frac{26.2}{1.3075}[/tex] mile per hour

Or ,  x = 20.038   mph

Hence The speed of marathon is 20.038 mile per hours  Answer
