Sure! Let’s solve each of the three time word problems step by step, and I’ll explain the reasoning clearly.

Problem 1:
> The train was scheduled to arrive at 5:10 p.m. However, it was delayed for 25 minutes. What time was it when the train arrived?
Solution:
We need to
add 25 minutes to the scheduled arrival time of
5:10 p.m.
- Start with 5:10 p.m.
- Add 25 minutes:
→ 10 minutes + 25 minutes = 35 minutes
→ So, the time becomes
5:35 p.m.
✔ Answer: 5:35 p.m.

Problem 2:
> The bus departs the bus terminal every 2 hours. If the first bus is scheduled to depart at 10:35 a.m., when should the second bus depart?
Solution:
Since buses leave
every 2 hours, we add
2 hours to the first departure time.
- First bus: 10:35 a.m.
- Add 2 hours:
→ 10:35 a.m. + 2 hours =
12:35 p.m.
✔ Answer: 12:35 p.m.
*(Note: After 11:35 a.m. comes 12:35 p.m. — don’t forget that 12:00 is noon, not 0:00.)*

Problem 3:
> The train left the terminal at 11:20 a.m. and arrived at its destination at 2:40 p.m. How long did the train travel?
Solution:
We need to find the
elapsed time between
11:20 a.m. and
2:40 p.m.
Let’s break this into parts:
Step 1: From 11:20 a.m. to 12:20 p.m. = 1 hour
Step 2: From 12:20 p.m. to 1:20 p.m. = another 1 hour → total so far: 2 hours
Step 3: From 1:20 p.m. to 2:20 p.m. = another 1 hour → total so far: 3 hours
Step 4: From 2:20 p.m. to 2:40 p.m. = 20 minutes
→ Total travel time =
3 hours + 20 minutes = 3 hours 20 minutes
✔ Answer: 3 hours and 20 minutes
*(Alternatively, you can subtract directly:
2:40 p.m. – 11:20 a.m.
= (2 hours – 11 hours) doesn’t work directly, so convert to 24-hour time or count up as above.)*

✔ Final Answers:
1.
5:35 p.m.
2.
12:35 p.m.
3.
3 hours and 20 minutes
