Let’s go through each problem one by one and calculate the time durations or end times carefully.

Problem 1:
Sam starts from home at 6:30 a.m. and reaches school at 7:25 a.m.
We need to find how long that took.
From 6:30 a.m. to 7:00 a.m. = 30 minutes
From 7:00 a.m. to 7:25 a.m. = 25 minutes
Total = 30 + 25 =
55 minutes
✔ Check: 6:30 + 55 min = 7:25 → Correct.

Problem 2:
Cricket match started at 10:15 a.m. and ended at 5:50 p.m.
First, convert 5:50 p.m. to 24-hour format for easier calculation? Or just count forward.
From 10:15 a.m. to 12:15 p.m. = 2 hours
From 12:15 p.m. to 5:15 p.m. = 5 hours
So far: 2 + 5 = 7 hours
Now from 5:15 p.m. to 5:50 p.m. = 35 minutes
Total = 7 hours + 35 minutes =
7 hours 35 minutes
✔ Check: 10:15 a.m. + 7h35m = 5:50 p.m. → Correct.

Problem 3:
Airplane leaves at 1:10 a.m. and arrives at 2:00 p.m.
From 1:10 a.m. to 1:10 p.m. = 12 hours
From 1:10 p.m. to 2:00 p.m. = 50 minutes
Total = 12 hours + 50 minutes =
12 hours 50 minutes
✔ Check: 1:10 a.m. + 12h50m = 2:00 p.m. → Correct.

Problem 4:
School interval starts at 10:45 a.m. and lasts 20 minutes. When does it end?
Add 20 minutes to 10:45 a.m.
10:45 + 15 minutes = 11:00 a.m.
Then add remaining 5 minutes → 11:05 a.m.
✔ Check: 10:45 + 20 min = 11:05 → Correct.

Final Answer:
1. 55 minutes
2. 7 hours 35 minutes
3. 12 hours 50 minutes
4. 11:05 a.m.
