###Human: Each week, Paul has 2 hours of homework on weeknights and 5 hours for the entire weekend. This week Paul has practice 2 nights out of the week and can't do any homework those nights. How many hours of homework does he have to average for the other nights to get his week's homework done?, ### Assistant: Paul has 10 hours of homework from weekdays because 2 x 5 = 10
He has 15 total hours because 5 + 10 = 15
He has 5 days to do his homework because 7 - 2 = 5
He needs to do 3 hours a night because 15 / 5 = 3 
 So the answer is :  3
