To find the elapsed time, we count how many hours pass from the Start Time to the End Time.
Here is the step-by-step calculation for each problem:
1)
2:00 A.M. to 6:00 A.M.
- Count up: 3, 4, 5, 6.
- That is 4 hours.
2)
1:00 P.M. to 8:00 P.M.
- Count up: 2, 3, 4, 5, 6, 7, 8.
- That is 7 hours.
3)
3:00 A.M. to 9:00 A.M.
- Count up: 4, 5, 6, 7, 8, 9.
- That is 6 hours.
4)
5:00 P.M. to 9:00 P.M.
- Count up: 6, 7, 8, 9.
- That is 4 hours.
5)
1:00 A.M. to 9:00 A.M.
- Count up: 2, 3, 4, 5, 6, 7, 8, 9.
- That is 8 hours.
6)
8:00 A.M. to Noon
- "Noon" means 12:00 P.M.
- Count up from 8: 9, 10, 11, 12.
- That is 4 hours.
7)
6:00 P.M. to 11:00 P.M.
- Count up: 7, 8, 9, 10, 11.
- That is 5 hours.
8)
2:00 A.M. to 3:00 A.M.
- From 2 to 3 is just 1 hour.
9)
3:00 A.M. to 11:00 A.M.
- Count up: 4, 5, 6, 7, 8, 9, 10, 11.
- That is 8 hours.
10)
2:00 P.M. to 8:00 P.M.
- Count up: 3, 4, 5, 6, 7, 8.
- That is 6 hours.
11)
4:00 P.M. to 6:00 P.M.
- Count up: 5, 6.
- That is 2 hours.
12)
5:00 A.M. to 8:00 A.M.
- Count up: 6, 7, 8.
- That is 3 hours.
13)
2:00 P.M. to 10:00 P.M.
- Count up: 3, 4, 5, 6, 7, 8, 9, 10.
- That is 8 hours.
14)
4:00 A.M. to 9:00 A.M.
- Count up: 5, 6, 7, 8, 9.
- That is 5 hours.
15)
Noon to 11:00 P.M.
- "Noon" is 12:00 P.M.
- Count up from 12: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11.
- That is 11 hours.
