1.Olivia travels 80 km in 40 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.6667 h
- speed = distance ÷ time = 80 ÷ 0.6667
- = 120 km/h
2.Kai travels 75 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 1.25 h
- speed = distance ÷ time = 75 ÷ 1.25
- = 60 km/h
3.A train travels at 60 km/h for 20 minutes. How far does it travel?
Answer: 20 km
- time = 0.3333 h
- distance = speed × time = 60 × 0.3333
- = 20 km
4.A train travels at 90 km/h for 40 minutes. How far does it travel?
Answer: 60 km
- time = 0.6667 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.
