Solution :

According to the question,

Time taken by Jesse to run 1 mile = 7 minutes

Also,

Time taken by Jesse to run 1 mile = 2½ minutes + Michael's time

Now, we can say that :

⇒ 7 minutes = 2½ minutes + Michael's time

⇒ (7 - 2½) minutes = Michael's time

⇒ (7 - 5/2) minutes = Michael's time

⇒ (14 - 5)/2 minutes = Michael's time

⇒ 9/2 minutes = Michael's time

⇒ 4½ minutes = Michael's time [Answer]
