What a question looks like
Example questionHow much time passes from 08:01 to 10:46? Use a 24-hour clock.
Answer: 2 h 45 min
- Count forward 2 hours and 45 minutes from 08:01 to 10:46.
- The elapsed time is 2 h 45 min.
Use this practice well
Count from the start time to the next full hour, then add whole hours and remaining minutes. Check the result by adding the duration back to the start.
What this develops
Find how many hours and minutes pass between two stated times, including next-day cases.
A mistake to watch for
Subtracting clock digits as though minutes were base ten gives the wrong interval.
Ways to use it
- Practise real schedules.
- Review conversions across an hour.
- Discuss a next-day journey.
Scope and limits
Times use the 24-hour clock and durations are less than eleven hours.
