Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 90 km/h for 40 minutes. How far does it travel?
Answer: 60 km
- time = 0.6667 h
- distance = speed × time = 90 × 0.6667
- = 60 km
2.Priya travels 90 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 1.5 h
- speed = distance ÷ time = 90 ÷ 1.5
- = 60 km/h
3.A car travels 100 km at an average speed of 120 km/h. How long does the trip take?
Answer: 50 minutes
- time = distance ÷ speed = 100 ÷ 120
- = 0.8333 h = 50 minutes
4.A car travels 20 km at an average speed of 60 km/h. How long does the trip take?
Answer: 20 minutes
- time = distance ÷ speed = 20 ÷ 60
- = 0.3333 h = 20 minutes
5.Hunter travels 20 km in 40 minutes. What is the average speed in km/h?
Answer: 30 km/h

- = 30 km/h
6.Oliver travels 80 km in 40 minutes. What is the average speed in km/h?
Answer: 120 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.
