conversations.value: Please show me the solution for: Casey takes 6 hours to complete a marathon race, while Zendaya takes 1/3 times longer to cover the same distance. What is the average time the two take to complete to race?

conversations.value: Zendaya takes 1/3 * 6 hours = 2 hours longer to complete the marathon.
  To complete the marathon, Zendaya takes 6 hours + 2 hours = 8 hours
  The combined time the two take to complete the marathon is 8 hours + 6 hours = 14 hours
  The average number of hours Casey and Zendaya take to complete the marathon is 14 hours / 2 people = 7 hours/person.
