conversations.value: I'm stuck on this math problem: John wants to finish a show in 5 days.  There are 20 episodes and they are each 30 minutes long.  How many hours does he have to watch a day?
  Can you help?
conversations.from: assistant
conversations.value: He wants to watch 20*30=600 minutes
  So he needs to watch 600/60=10 hours
  That means he needs to watch 10/5=2 hours a day
