Question

If Usain Bolt can run a marathon (26.2) in 2 hours and 15 minutes, how fast would he run if he ran at the same constant rate?

Answer 1

The speed of Usain Bolt is 0.194 miles per minutes to complete the marathon.

Explanation:

Given as :

The Distance of marathon = 26.2 unit

The time taken to complete marathon = 2 hours and 15 minutes

= 120 + 15 = 135 minutes

Let The constant speed of Usain Bolt = S unit per minutes

So, Speed =
`(Distance )/(Time)`

Or, S =
`(26.2 )/(135)`

∴ S = 0.194 unit per minutes

Hence The speed of Usain Bolt is 0.194 miles per minutes to complete the marathon. Answer
