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

Answer:

249.5 minutes

Explanation:

Ali's speed is given by:

$v=\frac{d}{t}$

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

$v=\frac{12 mi}{114 min}=0.105 mi/min$

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

$t = \frac{L}{v}=\frac{26.2 mi}{0.105 mi/min}=249.5 min$
