1.Layla travels 18.75 km in 45 minutes. What is the average speed in km/h?
Answer: 25 km/h
- time = 0.75 h

- = 25 km/h
2.A train travels at 70 km/h for 45 minutes. How far does it travel?
Answer: 52.5 km
- time = 0.75 h
- distance = speed × time = 70 × 0.75
- = 52.5 km
3.Jayden travels 17.5 km in 30 minutes. What is the average speed in km/h?
Answer: 35 km/h
- time = 0.5 h

- = 35 km/h
4.A car travels 52.5 km at an average speed of 70 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 52.5 ÷ 70
- = 0.75 h = 45 minutes
5.A car travels 105 km at an average speed of 70 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 105 ÷ 70
- = 1.5 h = 1 hour 30 minutes
6.A train travels at 75 km/h for 15 minutes. How far does it travel?
Answer: 18.75 km

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.
