1.Zoe travels 80 km in 40 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.6667 h

- = 120 km/h
2.Aisha travels 50 km in 50 minutes. What is the average speed in km/h?
Answer: 60 km/h

- speed = distance ÷ time = 50 ÷ 0.8333
- = 60 km/h
3.A train travels at 30 km/h for 45 minutes. How far does it travel?
Answer: 22.5 km
- time = 0.75 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.
