Elapsed time worksheet for 3 - Free Printable

Explanation:
We need to read the times shown on each analog clock (A and B), write them in digital form (e.g., 9:30), and then find how much time passed between Clock A and Clock B.

Let’s go row by row.

First set (top row):

- Clock A: Hour hand is halfway between 9 and 10 → it’s 9. Minute hand points at 6 → that’s 30 minutes (since each number = 5 minutes; 6 × 5 = 30). So time = 9:30.
- Clock B: Hour hand is just past 12, minute hand at 6 → 12:30. So time = 12:30.
- Time elapsed: From 9:30 to 12:30 = 3 hours → 3 hours (or 180 minutes). But since the question says “How much time has elapsed”, and the other answers are likely in hours/minutes format, we’ll write as 3 hours or 3:00, but let’s see pattern — usually they expect digital time difference like “3:00” or just “3 hours”. Since the blank is a line, and earlier blanks are digital times (e.g., 9:30), for elapsed time, it's common to write in hours:minutes (e.g., 3:00). We'll use 3:00.

Wait — double-check: Is Clock B really 12:30? Yes: hour hand slightly past 12 (not at 1 yet), minute hand at 6 → 30 minutes → 12:30.

So:
- A: 9:30
- B: 12:30
- Elapsed: 12:30 − 9:30 = 3:00

Second set (middle row):

- Clock A: Hour hand between 11 and 12, closer to 12; minute hand at 4 → 4 × 5 = 20 minutes. So time = 11:20.
- Clock B: Hour hand between 2 and 3, closer to 2; minute hand at 4 → 20 minutes. So time = 2:20.
- Now, elapsed time: From 11:20 to 2:20 next day? No — since it's a worksheet for Primary Three, likely same day, so we assume Clock B is *later* that day. So from 11:20 AM to 2:20 PM = 3 hours. Or if both are AM, 2:20 is after 11:20 only if it's next day — but in school problems like this, they usually mean Clock B is later on the same 12-hour cycle, so 11:20 → 12:00 = 40 min, then 12:00 → 2:20 = 2h20m, total = 3h00m → 3:00 again.

But wait — let’s verify positions:
- Clock A: hour hand just before 12 (pointing near 11.5), minute at 4 → yes, 11:20.
- Clock B: hour hand just past 2 (so ~2:20), minute at 4 → 2:20.
So difference = 3 hours exactly. ✔

Third set (bottom row):

- Clock A: Hour hand pointing at 9, minute hand at 12 → that’s 9:00.
- Clock B: Hour hand just past 12, minute hand at 9 → 9 × 5 = 45 minutes → 12:45.
- Elapsed time: From 9:00 to 12:45 = 3 hours 45 minutes → 3:45.

Let’s double-check all:

1. Top:
- A: hour hand between 9 & 10, minute at 6 → 9:30 ✔️
- B: hour just past 12, minute at 6 → 12:30 ✔️
- Diff: 12:30 − 9:30 = 3:00 ✔️

2. Middle:
- A: hour near 11.5 (i.e., 11 + 20/60 = 11:20), minute at 4 → 20 min → 11:20 ✔️
- B: hour near 2.33 (2 + 20/60), minute at 4 → 20 min → 2:20 ✔️
- From 11:20 to 2:20 = 3 hours ✔️ → 3:00

3. Bottom:
- A: hour at 9, minute at 12 → 9:00 ✔️
- B: hour just past 12, minute at 9 → 45 min → 12:45 ✔️
- 12:45 − 9:00 = 3h45m → 3:45

All correct.

Final Answer:
Clock A: 9:30
Clock B: 12:30
Elapsed: 3:00

Clock A: 11:20
Clock B: 2:20
Elapsed: 3:00

Clock A: 9:00
Clock B: 12:45
Elapsed: 3:45
