Twelve hours and thirty minutes (12:30) pass between 9:30 a.m. and 10:00 p.m. An easy way to figure this out is to add twelve hours to the later time (in this case, 10:00 p.m.) and then subtract the earlier time from it. In this case, this means you would add 12:00 to 10:00 to get 22:00; subtracting 9:30 from 22:00 gives 12:30.
9 hours.
There are (7.5 + 24k) hours where k is an integer.

12 p.m to 9:30 p.m is 10 hours and 30 minutes......... :)
7 hours 15 minutes
5.5 + 24k where k is any integer.
There are 16 hours from 9 PM to 1 PM the next day.
To find the answer, subtract 9:30 from 11:40. The answer is 2 hours and 10 minutes.
