Sagot :

Answer:

4 hours and 20 minutes

Step-by-step explanation:

Just follow the instruction

15 hours and 12 minutes

10 hours and 52 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.
