Apple can run at a rate of 3 miles per hour. Mac can run at a rate of 4 miles per hour. In minutes, how much faster will Mac run a 24 mile race?
Reason slowly and give your answer.
120
First find how fast each runs.

Apple = 24 miles / 3 miles per hour = 8 hours.

Mac = 24 miles / 4 miles per hour = 6 hours.

Mac runs 8 hours - 6 hours = 2 hours faster.

1 hour = 60 minutes, so, Mac runs faster by 2 hours * 60 minutes = 120 minutes.

The answer: 120
