conversations.value: Find a solution for this math problem: Mr. John jogs for 1 hour 30 minutes in the morning every day. How much time (in hours) will he have spent jogging after two weeks?
conversations.from: assistant
conversations.value: There are 60 minutes in an hour so 1 hour 30 minutes is equivalent to [1 + (30/60)] hours = 1.5 hours
  There are 7 days in a week so he spends 1.5*7 = 10.5 hours jogging every week
  After 2 weeks he will have spent 2*10.5 = 21 hours jogging.
