Question: Percy swims 1 hour before school and 1 after school 5 days a week. He swims 3 hours on the weekend. How many hours of swimming does he do over 4 weeks?
Answer with step-by-step thinking: He swims 1 hour before and after school for a total of 1 + 1 = 2 hours. He swims 2 hours a day for 5 days for a total of 2 * 5 = 10 hours. He also swims an additional 3 hours on the weekend so 10 + 3 = 13 hours. Over a course of 4 weeks, at 13 hours per week, he swims 4 * 13 = 52 hours.
So the answer is 52.
