Question: Marcus spends 20 minutes giving his dog a bath and half as long blow-drying her. Then he takes her for a walk along a 3-mile trail. If Marcus walks at 6 miles per hour, how much time does he spend with his dog total?
Answer:
First find the total amount of time Marcus spends blow - drying his dog: 20 minutes / 2 = 10 minutes. Then find the time Marcus spends walking: 3 miles / 6 miles / hour = .5 hours. Then convert that time to minutes: .5 hours * 60 minutes / hour = 30 minutes. Then add up the time Marcus spends washing, drying and walking to find the total time: 10 minutes + 20 minutes + 30 minutes = 60 minutes. The answer is 60.
