conversations.value: Chuck can ride the merry-go-round 5 times longer than Dave who can only ride it for 10 minutes before getting sick.  Erica can stay on the merry-go-round 30% longer than Chuck before getting sick.  How long can Erica stay on the merry-go-round?
  Give me a clear explanation.

conversations.value: Dave can ride the merry-go-round for 10 minutes and Chuck can ride 5 times longer than Dave so he can ride for 10*5 = 50 minutes
  Erica can stay on 30% longer than Chuck who can ride for 50 minutes so that's an extra .30*50 = 15 minutes
  Chuck can ride for 50 minutes and Erica can ride an extra 15 minutes for a total of 50+15 = 65 minutes
