1.A car travels 85 km at an average speed of 85 km/h. How long does the trip take?
Answer: 1 hour
- time = distance ÷ speed = 85 ÷ 85
- = 1 h = 1 hour
2.Harper travels 190 km in 2 hours. What is the average speed in km/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.
