conversations.value: Jamie is a firefighter. One day an emergency call comes in from Mrs. Thompson, an elderly woman whose cat can't get down a 20-foot tree. The last time Jamie rescued a cat, he got it down from a 6-foot tree and had to climb 12 rungs of his ladder. How many rungs does he have to climb this time to get the cat down from the tree?
conversations.from: assistant
conversations.value: Jamie needed 12/6 = 2 rungs per foot of the tree to save the first cat.
  To climb a 20-foot tree, Jamie needs 20*2 = 40 rungs
