Question

Ali is training for a marathon he knows he can run 12 miles in 114 minutes if he keeps this pace how long will it take him to run the marathon? ​

Answer 1

249.5 minutes

Step-by-step explanation:

Ali's speed is given by:

`v=(d)/(t)`

where

d is the distance covered

t is the time taken

We know that he can run d = 12 mi in t = 114 min, so he can keep a speed of

`v=(12 mi)/(114 min)=0.105 mi/min`

The length of a maraton is

L = 26.2 miles

So we can find the time it takes for Ali to complete the marathon as follows

`t = (L)/(v)=(26.2 mi)/(0.105 mi/min)=249.5 min`
