Answer:
35 minutes
Explanation:
First, we can convert everything to minutes.
10/12 of an hour
60 minutes = 1 hour
1/12 of an hour = 60/12 minutes = 5 minutes
10/12 of an hour = 1/12 of an hour * 10 = 50 minutes
1/4 hour = 1/4 of 60 minutes = 15 minutes
time doing daily exercises - time doing hiking = time doing other body exercises = 50 minutes - 15 minutes = 35 minutes
