Question: Sherman has a 30-minute commute to the office and a 30-minute commute home every day. On the weekends, he spends 2 hours, each day, driving his kids to their different activities. How many hours does Sherman drive a week?
Answer with step-by-step thinking: He drives 30 minutes to work and 30 minutes home every day for a total of 30 + 30 = 60 minutes. He makes this drive 5 days a week for a total of 5 * 60 = 300 minutes. There are 60 minutes in 1 hour and he drives 300 minutes, 5 days a week so that's 300 / 60 = 5 hours. He drives 2 hours on both Saturday and Sunday so he drives 2 * 2 = 4 hours on the weekends. He commutes 5 hours during the week and spends 4 hours driving on the weekend for a total of 5 + 4 = 9 hours.
So the answer is 9.
