Consider the question. Jim spends 8 hours scuba diving. In that time he finds a treasure chest with 100 gold coins in it. He also finds 2 smaller bags that have half as much gold each. How much gold does he find per hour?
 If the answer is '25'; explain the reasoning:
The smaller bags each have 100 / 2 = 50 gold coins each. So in total, they have 50 * 2 = 100 coins. So he found 100 + 100 = 200 coins. So he finds 200 / 8 = 25 coins an hour.
