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
