Question

Hunter wanted to make a poster for Save Your Smile Week. He thought it would be fun to put how many minutes someone might spend brushing and flossing each year on the poster. If a person spends 20 minutes per day brushing and flossing, how long would that person spend in a year? (Use 365 days for one year.)

Answer 1

20 min/day * 365 days = 7300 min
7300 min * 1 hour/ 60 min) = 730/6 = 365/3 hours = 121 2/3 hours
= 121 hours 40 minutes
