Explanation:
We need to find how much time passed between the “Start” and “End” times for each row. We’ll calculate elapsed time in hours and minutes.
Remember:
- From any time to the same time next day is 24 hours.
- Midnight is 12:00 A.M., and noon is 12:00 P.M.
- When crossing midnight (e.g., 4:00 P.M. to 12:00 A.M.), we go from P.M. to A.M., so we count hours until 12:00 A.M.
Let’s do each one carefully:
1.
4:00 P.M. to 12:00 A.M.
From 4:00 P.M. to 12:00 A.M. =
4:00 P.M. → 5:00 P.M. (1 hr)
→ 6:00 P.M. (2)
→ 7:00 P.M. (3)
→ 8:00 P.M. (4)
→ 9:00 P.M. (5)
→ 10:00 P.M. (6)
→ 11:00 P.M. (7)
→ 12:00 A.M. (8 hrs)
✔ 8 hours, 0 minutes
2.
7:30 P.M. to 9:30 P.M.
Same day, just subtract:
9:30 − 7:30 = 2 hours
✔ 2 hours, 0 minutes
3.
1:00 P.M. to 7:00 P.M.
7 − 1 = 6 hours
✔ 6 hours, 0 minutes
4.
12:00 P.M. to 5:00 P.M.
5 − 12 = 5 hours
✔ 5 hours, 0 minutes
5.
3:30 P.M. to 9:30 P.M.
9:30 − 3:30 = 6 hours
✔ 6 hours, 0 minutes
6.
1:00 A.M. to 5:00 A.M.
5 − 1 = 4 hours
✔ 4 hours, 0 minutes
7.
7:00 A.M. to 10:00 A.M.
10 − 7 = 3 hours
✔ 3 hours, 0 minutes
8.
5:30 A.M. to 12:30 P.M.
From 5:30 A.M. to 12:30 P.M.:
5:30 A.M. → 12:30 P.M. = 7 hours
(Because 12:30 P.M. − 5:30 A.M. = 7:00)
✔ 7 hours, 0 minutes
9.
2:00 A.M. to 11:00 A.M.
11 − 2 = 9 hours
✔ 9 hours, 0 minutes
10.
2:00 A.M. to 12:00 P.M.
From 2:00 A.M. to 12:00 P.M. = 10 hours
(2 → 12 = 10 hrs)
✔ 10 hours, 0 minutes
11.
4:30 P.M. to 1:30 A.M.
This crosses midnight.
From 4:30 P.M. to 12:00 A.M. = 7.5 hours = 7 hrs 30 min
From 12:00 A.M. to 1:30 A.M. = 1 hr 30 min
Total = 7h30m + 1h30m = 9 hours
✔ 9 hours, 0 minutes
Let me double-check #11:
4:30 P.M. → 5:30 P.M. (1h)
→ 6:30 (2)
→ 7:30 (3)
→ 8:30 (4)
→ 9:30 (5)
→ 10:30 (6)
→ 11:30 (7)
→ 12:30 A.M. (7.5 h = 7h30m) — wait! That’s wrong — we only want to go to
12:00 A.M., not 12:30.
Correct:
4:30 P.M. to 12:00 A.M. =
4:30 → 5:30 (1)
→ 6:30 (2)
→ 7:30 (3)
→ 8:30 (4)
→ 9:30 (5)
→ 10:30 (6)
→ 11:30 (7)
→ 12:00 A.M. (7.5 h = 7 hrs 30 min)
Then 12:00 A.M. → 1:30 A.M. = 1 hr 30 min
Total = 7h30m + 1h30m =
9 hours exactly ✔
All others are whole hours — no minutes leftover.
Final Answer:
8 hours 0 minutes
2 hours 0 minutes
6 hours 0 minutes
5 hours 0 minutes
6 hours 0 minutes
4 hours 0 minutes
3 hours 0 minutes
7 hours 0 minutes
9 hours 0 minutes
10 hours 0 minutes
9 hours 0 minutes
