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? Give me reasons, before answering the question

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. So the final answer is 7.
