conversations.value: This math problem has got me stumped: John builds a model rocket that can travel 500 ft in the air.  He builds a second rocket that can travel twice as high.  What is the combined height of the two rockets?
  Can you show me the way?

conversations.value: The second rocket goes 500*2=1000 feet
  So the total height is 500+1000=1500 feet
