Michelle went on a hike. she started on the trail at 6: 45 am and returned at 3: 28 pm how long did she hike

6:45, 7:45, 8:45, 9:45, 10:45, 11:45, 12:45, 1:45, 2:45= 8 hours

2:45+15 minutes=3:00
3:00+28 minutes=3:28

So, 8 hours+15 minutes+28 minutes= 8 hours and 43 minutes.

Michelle hiked for 8 hours and 43 minutes.

The answer is 3 hours and 17 minutes.

45-28= 17
6-3= 3

Therefore the answer is 3 hours and 17 minutes
