Answer:
4 hours and 20 minutes

Just follow the instruction
15 hours and 12 minutes

Since 12 min-52 min is impossible,you need to borrow 1 hour from 15 hours so 15-1=14
Then that 1 hours should be converted to minutes to be added to 12 minutes so 1hour and 12 minutes is to 72 minutes so
14 hours and 72 minutes
-
10 hours and 52 minutes
is equal to 4 hours and 20 minutes thx.
