conversations.value: Since there are 60 seconds in 1 minute, then there are 60/30 = 2 sets of 30 seconds in a minute.
  So a wheel makes 6 x 2 = 12 turns in 1 minute.
  Since there are 60 minutes in 1 hour, then a wheel makes 12 x 60 = 720 turns in an hour.
  Therefore, the wheel makes 720 x 2 = 1440 turns in 2 hours.
