conversations.value: I would love to understand how to solve this problem: Kira's cat eats a pound of kibble every 4 hours. Kira fills her cat's bowl with 3 pounds of kibble before going to work. When she returns, Kira weighs the bowl and there is still 1 pound left. How many hours was Kira away from home?
  Can you explain?

conversations.value: Kira's cat has eaten 3 pounds - 1 pound = 2 pounds of kibble.
  Since the cat eats one pound of kibble every 4 hours, Kira has been out 4 hours * 2 pounds/hour = 8 hours.
