Question

Khalil is going on a hike to the top of a mountain. It will take 2 hours and 33 minutes to hike up the mountain and 49 minutes to hike back down. If Khalil wants to finish the hike by 2:58 P.M., what is the latest time he can start the hike up the mountain?

Answer 1

If Khalil wants to finish the hike by 2:58 P.M. and the hike up the mountain will take 2 hours and 33 minutes, then he needs to start the hike up the mountain at 12:25 P.M. (2:58 P.M. minus 2 hours and 33 minutes).

If the hike back down will take 49 minutes, then Khalil will finish the hike at 3:47 P.M. (2:58 P.M. plus 49 minutes).
