question: 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?
answer: He spends 6*60=<<6*60=360>>360 minutes dealing with calls
  So he deals with 360/15=<<360/15=24>>24 calls a day
  So he deals with 5*24=<<5*24=120>>120 calls a week
