[Question]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?
[Answer]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 is 9.
Q: Toby, the Alaskan Malamute, can pull a sled at a speed of 20 miles per hour if the sled is unloaded, but he pulls the same sled at a speed of 10 miles per hour if the sled is fully loaded. If Toby takes a continuous 4-part journey, first pulling the loaded sled for 180 miles, then pulling the unloaded sled for 120 miles, then pulling the loaded sled 80 miles, and finally, pulling the unloaded sled another 140 miles, how many hours in total will Toby spend pulling the sled?
A: Pulling a loaded sled at 10 mph for 180 miles takes 180 / 10 = 18 hours. Pulling an unloaded sled at 20 mph for 120 miles takes 120 / 20 = 6 hours. Pulling a loaded sled at 10 mph for 80 miles takes 80 / 10 = 8 hours. Pulling an unloaded sled at 20 mph for 140 miles takes 140 / 20 = 7 hours. In total, Toby will have pulled the sled for 18 + 6 + 8 + 7 = 39 hours. The answer is 39.
