Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Amelia travels 45 km in 45 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.75 h
- speed = distance ÷ time = 45 ÷ 0.75
- = 60 km/h
2.Sienna travels 25 km in 50 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.8333 h
- speed = distance ÷ time = 25 ÷ 0.8333
- = 30 km/h
3.A car travels 90 km at an average speed of 120 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 90 ÷ 120
- = 0.75 h = 45 minutes
4.A train travels at 90 km/h for 20 minutes. How far does it travel?
Answer: 30 km
- time = 0.3333 h
- distance = speed × time = 90 × 0.3333
- = 30 km
5.Mason travels 150 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 120 km/h

- speed = distance ÷ time = 150 ÷ 1.25
- = 120 km/h
6.A train travels at 120 km/h for 50 minutes. How far does it travel?
Answer: 100 km
- time = 0.8333 h
- distance = speed × time = 120 × 0.8333
- = 100 km
7.A car travels 45 km at an average speed of 60 km/h. How long does the trip take?
Answer: 45 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.
