Answer:
6 hours and 45 minutes
Step-by-step explanation:
First, convert 12 hours into minutes.
12*60=720
Convert 5 hours to minutes and add 15
5*60=300+15=315
Subtract 720 from 315.
720-315=405
Convert into hours and minutes.
405/60=6.75
0.75 of an hour is 45 minutes so the answer is 6 hours and 45 minutes.
