Elapsed Time Worksheet for Grade 3-exercise 2 (Answer Key Included - Free Printable

To solve the problem, we need to calculate the elapsed time between the "Start Time" and "End Time" for each row in the table. The elapsed time is the difference between the end time and the start time. Let's go through each row step by step.

Table Structure:

- Start Time: The time when an event begins.
- End Time: The time when an event ends.
- Elapsed Time: The duration of the event, calculated as `End Time - Start Time`.

Step-by-Step Solution:

#### Row 1:
- Start Time: 8:00 A.M.
- End Time: 10:30 A.M.
- Elapsed Time:
- From 8:00 A.M. to 10:00 A.M. is 2 hours.
- From 10:00 A.M. to 10:30 A.M. is 30 minutes.
- Total: 2 hours and 30 minutes (already filled).

#### Row 2:
- Start Time: 10:00 P.M.
- End Time: 11:30 P.M.
- Elapsed Time:
- From 10:00 P.M. to 11:00 P.M. is 1 hour.
- From 11:00 P.M. to 11:30 P.M. is 30 minutes.
- Total: 1 hour and 30 minutes.

#### Row 3:
- Start Time: 2:00 P.M.
- End Time: 5:00 P.M.
- Elapsed Time:
- From 2:00 P.M. to 5:00 P.M. is 3 hours.
- Total: 3 hours.

#### Row 4:
- Start Time: 12:30 P.M.
- End Time: 7:00 P.M.
- Elapsed Time:
- From 12:30 P.M. to 7:00 P.M. is 6 hours and 30 minutes.
- Total: 6 hours and 30 minutes.

#### Row 5:
- Start Time: 4:00 A.M.
- End Time: 11:00 A.M.
- Elapsed Time:
- From 4:00 A.M. to 11:00 A.M. is 7 hours.
- Total: 7 hours.

#### Row 6:
- Start Time: 3:00 P.M.
- End Time: 9:30 P.M.
- Elapsed Time:
- From 3:00 P.M. to 9:00 P.M. is 6 hours.
- From 9:00 P.M. to 9:30 P.M. is 30 minutes.
- Total: 6 hours and 30 minutes.

#### Row 7:
- Start Time: 4:30 P.M.
- End Time: 6:00 P.M.
- Elapsed Time:
- From 4:30 P.M. to 6:00 P.M. is 1 hour and 30 minutes.
- Total: 1 hour and 30 minutes.

#### Row 8:
- Start Time: 12:00 A.M.
- End Time: 12:00 P.M.
- Elapsed Time:
- From 12:00 A.M. to 12:00 P.M. is 12 hours.
- Total: 12 hours.

#### Row 9:
- Start Time: 1:00 P.M.
- End Time: 1:30 P.M.
- Elapsed Time:
- From 1:00 P.M. to 1:30 P.M. is 30 minutes.
- Total: 30 minutes.

Final Completed Table:

| Start Time | End Time | Elapsed Time |
|------------|------------|--------------------|
| 8:00 A.M. | 10:30 A.M. | 2 hours and 30 minutes |
| 10:00 P.M. | 11:30 P.M. | 1 hour and 30 minutes |
| 2:00 P.M. | 5:00 P.M. | 3 hours |
| 12:30 P.M. | 7:00 P.M. | 6 hours and 30 minutes |
| 4:00 A.M. | 11:00 A.M. | 7 hours |
| 3:00 P.M. | 9:30 P.M. | 6 hours and 30 minutes |
| 4:30 P.M. | 6:00 P.M. | 1 hour and 30 minutes |
| 12:00 A.M. | 12:00 P.M. | 12 hours |
| 1:00 P.M. | 1:30 P.M. | 30 minutes |
