conversations.value: Can you give me some step-by-step instructions for this math problem: John decides to do several activities while out on vacation.  He spends 6 hours boating and half that time swimming.  He also watched 3 different shows which were 2 hours each.  This was 30% of the time he spent.  He spent 40% of his time sightseeing.  How much time did he spend sightseeing?
conversations.from: assistant
conversations.value: He spent 6/2=3 hours swimming
  He spent 3*2=6 hours watching shows
  So he spent 6+3+6=15 hours on these activities
  That means he spent 15/.3=50 hours on activities
  So he spent 50*.4=20 hours sightseeing
