Time-Related Problems
You may be asked a time-related problem question. The question will be written in full sentences, which you will need to read carefully.
Example problem
- A film starts at 8.15pm and lasts for 90 minutes.
- I arrive 10 minutes early and leave 10 minutes late (as I lose my scarf and search for it).
- How long did I spend at the cinema altogether and what time did I leave?
Work out how long
- To work out the time spent at the cinema, add the extra time spent arriving and leaving to the length of the film.
- 90 + 10 + 10 = 110 minutes
Work out leaving time
- The film started at 8.15pm. To work out what time the film ended, add 90 minutes to 8.15pm.
- 90 minutes is 1.5 hours, so the film ended at 9.45pm.
- I left the cinema 10 minutes late.
- This means that I left the cinema 10 minutes after 9.45pm.
- I left the cinema at 9.55pm.
- This means that I left the cinema 10 minutes after 9.45pm.
