Joan wants to visit her family who live 480 miles away. If she drives at a rate of 60 mph and takes a lunch break taking 30 minutes, and 2 bathroom breaks taking 15 minutes each, how many hours did it take her to get there? Let's answer step by step:
User
The driving time is 480 / 60 = 8 hours. The time for breaks was 30 + 15 + 15 = 60 minutes. So she spent 60 / 60 = 1 hour for rest stops. So it took her 8 + 1 = 9 hours. The answer: 9.
