Dave hiked to the top of a mountain. He started the hike at 8:59 A.M. It took 2 hours and 35 minutes to get to the top of the mountain and 1 hour and 29 minutes to hike back down. What time was it when Dave finished the hike?

To find out what time it was when Dave finished the hike, we need to add the total hiking time to the start time.

Total hiking time = time to hike up + time to hike down
Total hiking time = 2 hours 35 minutes + 1 hour 29 minutes
Total hiking time = 4 hours 4 minutes

Adding the total hiking time of 4 hours 4 minutes to the start time of 8:59 A.M.:

8:59 A.M. + 4 hours 4 minutes = 12:03 P.M.

Therefore, Dave finished the hike at 12:03 P.M.

that isn't the right answer

I apologize for the mistake. Let's correct the calculation.

Total time taken to hike up = 2 hours 35 minutes
Total time taken to hike down = 1 hour 29 minutes

Total hiking time = 2 hours 35 minutes + 1 hour 29 minutes
Total hiking time = 4 hours 4 minutes

Adding the total hiking time of 4 hours 4 minutes to the start time of 8:59 A.M.:

8:59 A.M. + 4 hours 4 minutes = 1:03 P.M.

Therefore, Dave finished the hike at 1:03 P.M. Thank you for pointing out the error.
