Elapsed time worksheet for Grade 3 with six problems involving drawing clock hands to show past and future times.

Let's solve each of the elapsed time problems step by step. The task involves calculating times forward or backward from a given clock time, using 1-minute increments.

We'll go through each question one by one, determine the starting time from the clock shown, then calculate the new time based on the instruction (e.g., "1 hour 38 minutes ago" or "in 3 hours 5 minutes").

Question 1:

Clock shows: 10:20
Question: What time was it 1 hour 38 minutes ago?

- Start at 10:20
- Subtract 1 hour → 9:20
- Subtract 38 minutes → 9:20 - 38 min = 8:42

✔ Answer: 8:42

Question 2:

Clock shows: 1:45
Question: What time was it 2 hours 14 minutes ago?

- Start at 1:45
- Subtract 2 hours → 11:45 (previous day if needed, but we assume same day)
- Subtract 14 minutes → 11:45 - 14 min = 11:31

✔ Answer: 11:31

Question 3:

Clock shows: 7:15
Question: What time was it 2 hours 15 minutes ago?

- Start at 7:15
- Subtract 2 hours → 5:15
- Subtract 15 minutes → 5:00

✔ Answer: 5:00

Question 4:

Clock shows: 2:10
Question: What time will it be in 3 hours 5 minutes?

- Start at 2:10
- Add 3 hours → 5:10
- Add 5 minutes → 5:15

✔ Answer: 5:15

Question 5:

Clock shows: 6:40
Question: What time will it be in 5 hours 24 minutes?

- Start at 6:40
- Add 5 hours → 11:40
- Add 24 minutes → 11:40 + 24 min = 12:04 (next day)

✔ Answer: 12:04

---

Question 6:

Clock shows: 12:00 (noon)
Question: What time will it be in 5 hours 58 minutes?

- Start at 12:00
- Add 5 hours → 5:00
- Add 58 minutes → 5:58

✔ Answer: 5:58

---

✔ Final Answers:

1. 8:42
2. 11:31
3. 5:00
4. 5:15
5. 12:04
6. 5:58

🔍 Explanation Summary:

To solve these:
- Read the current time from the clock.
- For "ago", subtract the elapsed time.
- For "in", add the elapsed time.
- Be careful with borrowing (e.g., going from 1:10 back 20 minutes → 12:50).
- Use 12-hour format and handle transitions across midnight when necessary.

You would draw the hands on the second clock to show the calculated time.
