Let’s solve each problem one by one. We’ll calculate the time duration between two given times.

Problem 1:
Sam starts at 6:30 a.m. and reaches school at 7:25 a.m.
From 6:30 to 7:00 is
30 minutes.
From 7:00 to 7:25 is
25 minutes.
Total = 30 + 25 =
55 minutes
✔ Duration:
55 minutes

Problem 2:
Cricket match starts at 10:15 a.m. and ends at 5:50 p.m.
First, let’s break it into parts:
From 10:15 a.m. to 12:00 p.m. (noon):
→ From 10:15 to 11:15 = 1 hour
→ From 11:15 to 12:00 = 45 minutes
So that’s
1 hour 45 minutes
From 12:00 p.m. to 5:00 p.m. =
5 hours
From 5:00 p.m. to 5:50 p.m. =
50 minutes
Now add them all:
- Hours: 1 + 5 = 6 hours
- Minutes: 45 + 50 = 95 minutes → which is 1 hour 35 minutes
Total = 6 hours + 1 hour 35 minutes =
7 hours 35 minutes
✔ Duration:
7 hours 35 minutes

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
But it arrives at 2:00 p.m., so we need to go from 1:10 p.m. to 2:00 p.m. =
50 minutes
Wait — actually, better way:
From 1:10 a.m. to 12:10 p.m. = 11 hours
Then from 12:10 p.m. to 2:00 p.m. = 1 hour 50 minutes
Total = 11 hours + 1 hour 50 minutes =
12 hours 50 minutes
Alternatively:
From 1:10 a.m. to 2:00 p.m. is the same as:
From 1:10 a.m. to 1:10 p.m. = 12 hours
Then from 1:10 p.m. to 2:00 p.m. = 50 minutes
→ Total = 12 hours 50 minutes
✔ Flying time:
12 hours 50 minutes

Problem 4:
School interval begins at 10:45 a.m. and lasts 20 minutes.
Add 20 minutes to 10:45 a.m.
45 + 20 = 65 minutes → that’s 1 hour 5 minutes
So 10:45 + 20 min = 11:05 a.m.
✔ Interval ends at:
11:05 a.m.

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