Time and clocks — Maths Olympiad practice

How to solve it

Jump to the hour — “go to the next (or last) full hour first, then the rest of the minutes”

1. Minutes after: jump to the next full hour, then add the minutes that are left.
2. Minutes before: jump back to the full hour, then go back the rest.
3. How long: change both times to minutes, take away, then change back to hours and minutes (60 minutes = 1 hour).

Use it for: Clock questions, timetables, and “how long is the film” problems.

Worked example: What time will it be 35 minutes after 3:40? 4:15
