conversations.value: I'm stuck on this math problem: Tim spends 6 hours each day at work answering phones.  It takes him 15 minutes to deal with a call.  How many calls does he deal with during his 5 day work week?
  Can you help?
conversations.from: assistant
conversations.value: He spends 6*60=360 minutes dealing with calls
  So he deals with 360/15=24 calls a day
  So he deals with 5*24=120 calls a week
