Question

The record Boston marathon is 1 hour 18 minutes and 27 seconds what is the speed if it’s 26.2 miles long the marathon

Answer 1

The speed of marathon is 20.038 mile per hours

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 =
`( 1 + (18)/(60)+(27)/(3600))hours`

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 =
`(26.2)/(1.3075)` mile per hour

Or , x = 20.038 mph

Hence The speed of marathon is 20.038 mile per hours Answer
