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?
First find how fast each runs. Apple = 24 miles / 3 miles per hour = <T>divide(24, 3)=8.0 hours
Mac = 24 miles / 4 miles per hour = <T>divide(24, 4)=6.0 hours.
Mac runs 8 hours - 6 hours = <T>subtract(8, 6)=2 hours faster.
1 hour = 60 minutes, so, Mac runs faster by 2 hours * 60 minutes = <T>multiply(2, 60)=120 minutes.
