Elapsed time math worksheet with clock-based questions for students to solve.

Explanation:
Let’s solve each question one by one. We need to look at the clock shown, read the current time, then add the given elapsed time.

Question 1:
Clock shows: hour hand between 8 and 9 → it's 8 something.
Minute hand points at 3 → that’s 15 minutes (since each number is 5 minutes: 3 × 5 = 15).
So current time = 08:15.
Add “2 hours and 15 minutes”:
- 08:15 + 2 hours = 10:15
- 10:15 + 15 minutes = 10:30
✔ So answer is 10:30

Question 2:
Clock shows: hour hand just past 6 → it's 6 something.
Minute hand points at 3 → 15 minutes.
So current time = 06:15.
Add “1 hour and 35 minutes”:
- 06:15 + 1 hour = 07:15
- 07:15 + 35 minutes = 07:50 (because 15 + 35 = 50)
✔ So answer is 07:50

Question 3:
Clock shows: hour hand between 7 and 8 → it's 7 something.
Minute hand points at 6 → 6 × 5 = 30 minutes.
So current time = 07:30.
Add “1 hour and 45 minutes”:
- 07:30 + 1 hour = 08:30
- 08:30 + 45 minutes = 09:15 (30 + 45 = 75 minutes = 1 hour 15 min → 08:30 + 1h15m = 09:45? Wait — let’s double-check!)

Hold on — mistake here!
08:30 + 45 minutes:
- From 08:30 to 09:00 is 30 minutes
- Then 15 more minutes → 09:15
Yes! Because 30 + 45 = 75 minutes = 1 hour 15 minutes, so:
07:30 + 1h45m = 07:30 + 1h = 08:30, then +45m = 09:15
✔ So answer is 09:15

Now check the options for each:
1. Options: 09:30, 10:30, 10:15 → correct is 10:30
2. Options: 08:50, 07:45, 07:50 → correct is 07:50
3. Options: 09:15, 09:30, 08:15 → correct is 09:15

All match.

Final Answer:
10:30, 07:50, 09:15
