Answer:
7:15 am
Step-by-step explanation:
1. Add the times together by finding a common denominator
3/4 = 9/12
1/6 = 2/12
1/12 = 1/12
1/4 = 3/12
9/12 + 2/12 + 1/12 + 3/12 = 15/12
It took him 15/12 of an hour in total.
2. Convert to hours
15/12 = 1 3/12
3/12 = 1/4
1/4 of an hour is 15 minutes.
I took him a total of 1 hour and 15 minutes.
3. Subtract 1 hour and 15 minutes from 8:30
8:30 - 1:15 = 7:15
The answer to that is y = -6
