1.A train travels at 60 km/h for 50 minutes. How far does it travel?
Answer: 50 km
- time = 0.8333 h

- = 50 km
2.Priya travels 20 km in 40 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.6667 h
- speed = distance ÷ time = 20 ÷ 0.6667
- = 30 km/h
3.Mason travels 112.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 1.25 h
- speed = distance ÷ time = 112.5 ÷ 1.25
- = 90 km/h
4.A car travels 90 km at an average speed of 60 km/h. How long does the trip take?
Answer: 1 hour 30 minutes

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.
