conversations.value: 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?
conversations.from: assistant
conversations.value: 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
