1.Ava 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
2.A train travels at 120 km/h for 40 minutes. How far does it travel?
Answer: 80 km
- time = 0.6667 h
- distance = speed × time = 120 × 0.6667
- = 80 km
3.A car travels 40 km at an average speed of 120 km/h. How long does the trip take?
Answer: 20 minutes
- time = distance ÷ speed = 40 ÷ 120
- = 0.3333 h = 20 minutes
4.A train travels at 90 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 135 km
- time = 1.5 h
- distance = speed × time = 90 × 1.5
- = 135 km
5.Mason travels 180 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 120 km/h

- = 120 km/h
6.Priya travels 37.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 30 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.
