there are 60 minutes in 1 hour, so 1/4 of an hour is 60(1/4), namely 15 minutes.
11:20pm + 4 hours, is 11+4:20, namely 15:20, of course the time system only uses up to 12, so that has to be 3:20, and then we add the 15 minutes.
11+4: 20 + 15.........3:35am.
Just multiply or divide the ratio to get each number to 30.

Step-by-step explanation:
For this problem you'll get a number, find it's opposite and sum 96 to it. The equation used will be:
x = -x + 96
Where:
x = a number
-x = the opposite of x
So:
x = -x + 96
x + x = 96
2x = 96
x = 96 / 2
x = 48
And now, if you do the sum to prove your answer:
48 - 96 = -48
