Keegan is in school for 7.5 hours each day and he is taking 7 classes. He has history and chemistry classes for a combined total of 1.5 hours. How many minutes does Keegan spend in one of his other classes on average?
He has 7-2=<T>subtract(7, 2)=5 other classes
7.5 hours - 1.5 hours = <T>subtract(7.5, 1.5)=6.0 hours
6 hours = <T>multiply(6, 60)=360 minutes
360/5 = <T>divide(360, 5)=72.0 minutes
Keegan spends 72 minutes in one of his other classes.
