Final answer:
Jordan started his hike at 8:30 A.M., reached the top at 10:45 A.M., and after hiking back down for 1 hour and 30 minutes, he finished his hike at 12:15 P.M.
Step-by-step explanation:
Jordan started his hike at 8:30 A.M. and took 2 hours and 15 minutes to get to the top of the mountain. To calculate the time when he reached the top, we add 2 hours and 15 minutes to 8:30 A.M. This will result in:
- Adding 2 hours to 8:30 A.M. gives us 10:30 A.M.
- Adding 15 minutes to 10:30 A.M. gives us 10:45 A.M.
Now, for the hike back down, which took 1 hour and 30 minutes, we add this duration to the time he reached the top:
- Adding 1 hour to 10:45 A.M. gives us 11:45 A.M.
- Adding 30 minutes to 11:45 A.M. gives us 12:15 P.M.
Therefore, Jordan finished his hike at 12:15 P.M.
