- = 4 h = 4 hours
2.A car travels 190 km at an average speed of 95 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 190 ÷ 95
- = 2 h = 2 hours
3.A train travels at 25 km/h for 5 hours. How far does it travel?
Answer: 125 km
- time = 5 h

Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
