What is elapsed time?

Back

Elapsed time is the amount of time that passes from the start of an event to the end of that event.

Back

To calculate elapsed time, subtract the start time from the end time. If the end time is on the next day, adjust accordingly.

1 hour equals 60 minutes. When calculating elapsed time, convert hours to minutes if necessary.

If a movie starts at 2:10 PM and ends at 4:40 PM, how do you find the duration?

Back

Subtract the start time from the end time: 4:40 PM - 2:10 PM = 2 hours and 30 minutes.

Front

What is the total time taken if a person takes 35 minutes to do dishes, 25 minutes to eat, and 40 minutes to walk?

Back

Total time = 35 minutes + 25 minutes + 40 minutes = 100 minutes or 1 hour and 40 minutes.

To convert minutes into hours, divide the number of minutes by 60.

If a practice starts at 3:40 PM and lasts for 1 hour and 30 minutes, what time does it end?

Back

End time = Start time + Duration = 3:40 PM + 1 hour 30 minutes = 5:10 PM.

Front

How do you determine the start time if you know the end time and duration?

Back

Subtract the duration from the end time to find the start time.

What is the duration of a play that starts at 1:15 PM and ends at 3:30 PM?
