conversations.value: A Ferris wheel can accommodate 70 people in 20 minutes.  If the Ferris wheel is open from 1:00 pm until 7:00 pm, how many people will get to ride?
  Work out the solution step by step.

conversations.value: The Ferris wheel will be open for 7:00 - 1:00 = 6 hours.
  In one hour the wheel can ride 60 minutes / 20 minutes = 3 times the number of riders.
  The total per hour riders is 3 * 70 people = 210 people.
  If the ride is open 6 hours * 210 people = 1260 people can ride.
