wolverine [178]

Answer:

275 minutes 12 seconds

Step-by-step explanation:

Given that :

slowest running time per mile = 9 minutes and 14 seconds

fastest running time per mile = 7

minutes and 58 seconds.

To estimate the time taken to run 16 miles ;

We can cross multiply:

4*9 = 6x

6x = 36

Divide both sides by 6:

x = 6
