Let's solve each of these elapsed time problems step by step. The goal is to calculate how much time has passed between two given times.
We’ll break down the process:
General Strategy:
1. If both times are in the same period (A.M. or P.M.), subtract the earlier time from the later one.
2. If the times cross from A.M. to P.M. or vice versa, we can:
- Convert both times to 24-hour format (military time), or
- Break it into segments (e.g., from start to midnight, then from midnight to end).

Now let’s go through each problem:
---
1) 4:00 P.M. to 8:46 P.M.
Same period (P.M.) → Subtract:
8:46 – 4:00 =
4 hours 46 minutes
✔ Answer: 4 hours 46 minutes
---
2) 4:20 P.M. to 8:00 P.M.
8:00 – 4:20 =
From 4:20 to 8:00 is 3 hours and 40 minutes
✔ Answer: 3 hours 40 minutes
---
3) 5:20 A.M. to 10:09 A.M.
10:09 – 5:20 =
From 5:20 to 10:09 is 4 hours and 49 minutes
✔ Answer: 4 hours 49 minutes
---
4) 8:40 P.M. to 10:02 P.M.
10:02 – 8:40 =
1 hour 22 minutes
✔ Answer: 1 hour 22 minutes
---
5) 6:40 A.M. to 8:51 A.M.
8:51 – 6:40 =
2 hours 11 minutes
✔ Answer: 2 hours 11 minutes
---
6) 1:00 P.M. to 2:31 P.M.
2:31 – 1:00 =
1 hour 31 minutes
✔ Answer: 1 hour 31 minutes
---
7) 1:00 A.M. to 5:21 A.M.
5:21 – 1:00 =
4 hours 21 minutes
✔ Answer: 4 hours 21 minutes
---
8) 2:40 A.M. to 6:21 A.M.
6:21 – 2:40 =
3 hours 41 minutes
✔ Answer: 3 hours 41 minutes
---
9) 12:20 P.M. to 4:44 P.M.
4:44 – 12:20 =
4 hours 24 minutes
✔ Answer: 4 hours 24 minutes
---
10) 5:00 A.M. to 6:19 A.M.
6:19 – 5:00 =
1 hour 19 minutes
✔ Answer: 1 hour 19 minutes
---
11) 8:40 A.M. to 10:19 A.M.
10:19 – 8:40 =
1 hour 39 minutes
✔ Answer: 1 hour 39 minutes
---
12) 5:20 A.M. to 9:00 A.M.
9:00 – 5:20 =
3 hours 40 minutes
✔ Answer: 3 hours 40 minutes
---
13) 6:00 P.M. to 8:56 P.M.
8:56 – 6:00 =
2 hours 56 minutes
✔ Answer: 2 hours 56 minutes
---
14) 6:20 A.M. to 9:42 A.M.
9:42 – 6:20 =
3 hours 22 minutes
✔ Answer: 3 hours 22 minutes
---
15) 2:40 P.M. to 5:20 P.M.
5:20 – 2:40 =
2 hours 40 minutes
✔ Answer: 2 hours 40 minutes
---
