Let's solve each of the
elapsed time word problems step by step.

Problem 1:
Sam starts from home at 6:30 a.m. and reaches school at 7:25 a.m. What is the duration of time he has taken to reach school?
Step-by-step solution:
- Start time: 6:30 a.m.
- End time: 7:25 a.m.
We can break this down:
- From 6:30 a.m. to 7:30 a.m. = 60 minutes
- But Sam only goes until 7:25 a.m., so we subtract 5 minutes.
So, total time = 60 minutes - 5 minutes =
55 minutes
✔ Answer: 55 minutes

Problem 2:
A cricket match commenced at 10:15 a.m. and concluded at 5:50 p.m. Find the time duration of the cricket match.
Step-by-step solution:
- Start time: 10:15 a.m.
- End time: 5:50 p.m.
Convert both times to a 24-hour format or use hours and minutes:
From 10:15 a.m. to 5:15 p.m. = 7 hours
From 5:15 p.m. to 5:50 p.m. = 35 minutes
So total time = 7 hours + 35 minutes =
7 hours 35 minutes
✔ Answer: 7 hours 35 minutes

Problem 3:
An airplane leaves an airport at 1:10 a.m. and reaches another airport at 2:00 p.m. Find the flying time of the airplane.
Step-by-step solution:
- Start time: 1:10 a.m.
- End time: 2:00 p.m. (which is 14:00 in 24-hour format)
Break it into parts:
- 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 flying time = 12 hours + 50 minutes =
12 hours 50 minutes
✔ Answer: 12 hours 50 minutes

Problem 4:
The school interval begins at 10:45 a.m. The duration of the interval is 20 minutes. At what time does the interval end?
Step-by-step solution:

- Add 20 minutes
10:45 a.m. + 20 minutes = 11:05 a.m.
✔ Answer: 11:05 a.m.
