your answer would be 17 hours. you dont really need an equation for this, just count the number of hours.
Lets make this simple.

7am + 5hours is 12pm

12pm + 6hours is 6pm
                                   > 12 hours total
6pm + 6hours is 12am

Add up how many hours in all i added

12 + 5 = 17 hours.
