1.A train travels at 120 km/h for 1 hour. How far does it travel?
Answer: 120 km
- time = 1 h
- distance = speed × time = 120 × 1
- = 120 km
2.A train travels at 110 km/h for 2 hours. How far does it travel?
Answer: 220 km
- time = 2 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.
