1.A train travels at 30 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 37.5 km
- time = 1.25 h

- = 37.5 km
2.Isla 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
3.A train travels at 120 km/h for 45 minutes. How far does it travel?
Answer: 90 km
- time = 0.75 h

- = 90 km/h
5.A car travels 90 km at an average speed of 60 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 90 ÷ 60
- = 1.5 h = 1 hour 30 minutes
6.A train travels at 60 km/h for 20 minutes. How far does it travel?
Answer: 20 km
- time = 0.3333 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.
