Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 131.25 km at an average speed of 105 km/h. How long does the trip take?
Answer: 1 hour 15 minutes

- = 1.25 h = 1 hour 15 minutes
2.Ethan travels 105 km in 3 hours. What is the average speed in km/h?
Answer: 35 km/h
- time = 3 h
- speed = distance ÷ time = 105 ÷ 3
- = 35 km/h
3.Aisha travels 17.5 km in 15 minutes. What is the average speed in km/h?
Answer: 70 km/h
- time = 0.25 h
- speed = distance ÷ time = 17.5 ÷ 0.25
- = 70 km/h
4.Emma travels 75 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 50 km/h

- = 50 km/h
5.A train travels at 110 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 165 km
- time = 1.5 h
- distance = speed × time = 110 × 1.5
- = 165 km
6.A car travels 315 km at an average speed of 105 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 315 ÷ 105

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.
