Question: John wants to finish a show in 5 days. There are 20 episodes and they are each 30 minutes long. How many hours does he have to watch a day? Think carefully first, then make a decision:
He wants to watch 20 * 30 = 600 minutes. So he needs to watch 600 / 60 = 10 hours. That means he needs to watch 10 / 5 = 2 hours a day. So the answer is 2.
