Math worksheet for calculating elapsed time using a table format.

Let's solve the problem step by step. We are given a table with Start Time, End Time, and Elapsed Time columns, and we need to fill in the missing values in each row.

We'll go through each row one by one and calculate or determine the missing value based on the other two.

---

Row 1:

- End Time: 12:33 P.M.
- Elapsed Time: 1 hour & 33 minutes
- Find Start Time

To find the start time, subtract elapsed time from end time:

12:33 P.M. – 1 hour = 11:33 A.M.
11:33 A.M. – 33 minutes = 11:00 A.M.

✔ Start Time = 11:00 A.M.

---

Row 2:

- End Time: 7:35 A.M.
- Elapsed Time: 3 hours & 15 minutes
- Find Start Time

Subtract elapsed time from end time:

7:35 A.M. – 3 hours = 4:35 A.M.
4:35 A.M. – 15 minutes = 4:20 A.M.

✔ Start Time = 4:20 A.M.

---

Row 3:

- Start Time: 3:00 A.M.
- End Time: 4:34 A.M.
- Find Elapsed Time

From 3:00 A.M. to 4:34 A.M. is:

1 hour + 34 minutes = 1 hour & 34 minutes

✔ Elapsed Time = 1 Hour & 34 Minutes

---

Row 4:

- End Time: 10:34 P.M.
- Elapsed Time: 2 hours & 34 minutes
- Find Start Time

Subtract elapsed time from end time:

10:34 P.M. – 2 hours = 8:34 P.M.
8:34 P.M. – 34 minutes = 8:00 P.M.

✔ Start Time = 8:00 P.M.

---

Row 5:

- Start Time: 10:40 A.M.
- End Time: 2:16 P.M.
- Find Elapsed Time

Convert both times to minutes past midnight for easier calculation:

- 10:40 A.M. = 10 × 60 + 40 = 640 minutes
- 2:16 P.M. = 14 × 60 + 16 = 856 minutes

Elapsed time = 856 – 640 = 216 minutes

Now convert 216 minutes to hours and minutes:

216 ÷ 60 = 3 hours and 36 minutes

✔ Elapsed Time = 3 Hours & 36 Minutes

---

Row 6:

- Start Time: 1:00 P.M.
- End Time: 3:55 P.M.
- Find Elapsed Time

From 1:00 P.M. to 3:55 P.M.:

2 hours + 55 minutes = 2 hours & 55 minutes

✔ Elapsed Time = 2 Hours & 55 Minutes

---

Row 7:

- End Time: 9:46 P.M.
- Elapsed Time: 3 hours & 26 minutes
- Find Start Time

Subtract elapsed time:

9:46 P.M. – 3 hours = 6:46 P.M.
6:46 P.M. – 26 minutes = 6:20 P.M.

✔ Start Time = 6:20 P.M.

---

Row 8:

- Start Time: 5:00 P.M.
- End Time: 8:38 P.M.
- Find Elapsed Time

From 5:00 P.M. to 8:38 P.M.:

3 hours + 38 minutes = 3 hours & 38 minutes

✔ Elapsed Time = 3 Hours & 38 Minutes

---

Row 9:

- End Time: 5:00 P.M.
- Elapsed Time: 3 hours & 40 minutes
- Find Start Time

Subtract elapsed time:

5:00 P.M. – 3 hours = 2:00 P.M.
2:00 P.M. – 40 minutes = 1:20 P.M.

✔ Start Time = 1:20 P.M.

---

Row 10:

- Start Time: 9:40 P.M.
- Elapsed Time: 4 hours & 44 minutes
- Find End Time

Add elapsed time to start time:

9:40 P.M. + 4 hours = 1:40 A.M. (next day)
1:40 A.M. + 44 minutes = 2:24 A.M.

✔ End Time = 2:24 A.M.

---

Final Completed Table:

| Start Time | End Time | Elapsed Time |
|----------------|----------------|----------------------|
| 11:00 A.M. | 12:33 P.M. | 1 Hour & 33 Minutes |
| 4:20 A.M. | 7:35 A.M. | 3 Hours & 15 Minutes |
| 3:00 A.M. | 4:34 A.M. | 1 Hour & 34 Minutes |
| 8:00 P.M. | 10:34 P.M. | 2 Hours & 34 Minutes |
| 10:40 A.M. | 2:16 P.M. | 3 Hours & 36 Minutes |
| 1:00 P.M. | 3:55 P.M. | 2 Hours & 55 Minutes |
| 6:20 P.M. | 9:46 P.M. | 3 Hours & 26 Minutes |
| 5:00 P.M. | 8:38 P.M. | 3 Hours & 38 Minutes |
| 1:20 P.M. | 5:00 P.M. | 3 Hours & 40 Minutes |
| 9:40 P.M. | 2:24 A.M. | 4 Hours & 44 Minutes |
