Elapsed Time Worksheets - Free Printable

To solve the problem of finding the elapsed time for each given start and end time, we need to calculate the difference between the two times. Here's how we can approach each problem step by step:

General Steps:

1. Identify the Start Time and End Time.
2. Calculate the difference in hours:
- If both times are in the same period (AM or PM), simply subtract the start time from the end time.
- If the times span across AM and PM (e.g., from 4:00 P.M. to 9:00 A.M.), calculate the time until midnight and then add the remaining time after midnight.

Detailed Solutions:

#### 1) Start Time: 2:00 A.M., End Time: 6:00 A.M.
- Both times are in the same period (A.M.).
- Elapsed Time = 6:00 A.M. - 2:00 A.M. = 4 hours.

#### 2) Start Time: 1:00 P.M., End Time: 8:00 P.M.
- Both times are in the same period (P.M.).
- Elapsed Time = 8:00 P.M. - 1:00 P.M. = 7 hours.

#### 3) Start Time: 3:00 A.M., End Time: 9:00 A.M.
- Both times are in the same period (A.M.).
- Elapsed Time = 9:00 A.M. - 3:00 A.M. = 6 hours.

#### 4) Start Time: 5:00 P.M., End Time: 9:00 P.M.
- Both times are in the same period (P.M.).
- Elapsed Time = 9:00 P.M. - 5:00 P.M. = 4 hours.

#### 5) Start Time: 1:00 A.M., End Time: 9:00 A.M.
- The times span across A.M. and P.M.
- From 1:00 A.M. to 12:00 A.M. (midnight): 1 hour.
- From 12:00 A.M. to 9:00 A.M.: 9 hours.
- Total Elapsed Time = 1 + 9 = 10 hours.

#### 6) Start Time: 8:00 A.M., End Time: Noon
- Both times are in the same period (A.M. to P.M.).
- Elapsed Time = Noon (12:00 P.M.) - 8:00 A.M. = 4 hours.

#### 7) Start Time: 6:00 P.M., End Time: 11:00 P.M.
- Both times are in the same period (P.M.).
- Elapsed Time = 11:00 P.M. - 6:00 P.M. = 5 hours.

#### 8) Start Time: 2:00 A.M., End Time: 3:00 A.M.
- Both times are in the same period (A.M.).
- Elapsed Time = 3:00 A.M. - 2:00 A.M. = 1 hour.

#### 9) Start Time: 3:00 A.M., End Time: 11:00 A.M.
- The times span across A.M. and P.M.
- From 3:00 A.M. to 12:00 A.M. (midnight): 9 hours.
- From 12:00 A.M. to 11:00 A.M.: 11 hours.
- Total Elapsed Time = 9 + 11 = 18 hours.

#### 10) Start Time: 2:00 P.M., End Time: 8:00 P.M.
- Both times are in the same period (P.M.).
- Elapsed Time = 8:00 P.M. - 2:00 P.M. = 6 hours.

#### 11) Start Time: 4:00 P.M., End Time: 6:00 P.M.
- Both times are in the same period (P.M.).
- Elapsed Time = 6:00 P.M. - 4:00 P.M. = 2 hours.

#### 12) Start Time: 5:00 A.M., End Time: 8:00 A.M.
- Both times are in the same period (A.M.).
- Elapsed Time = 8:00 A.M. - 5:00 A.M. = 3 hours.

#### 13) Start Time: 2:00 P.M., End Time: 10:00 P.M.
- Both times are in the same period (P.M.).
- Elapsed Time = 10:00 P.M. - 2:00 P.M. = 8 hours.

#### 14) Start Time: 4:00 A.M., End Time: 9:00 A.M.
- Both times are in the same period (A.M.).
- Elapsed Time = 9:00 A.M. - 4:00 A.M. = 5 hours.

#### 15) Start Time: Noon, End Time: 11:00 P.M.
- Both times are in the same period (P.M.).
- Elapsed Time = 11:00 P.M. - Noon (12:00 P.M.) = 11 hours.
