Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 237.5 km at an average speed of 95 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 237.5 ÷ 95
- = 2.5 h = 2 hours 30 minutes
2.A car travels 270 km at an average speed of 90 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 270 ÷ 90
- = 3 h = 3 hours
3.Grace travels 25 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 20 km/h
- time = 1.25 h
- speed = distance ÷ time = 25 ÷ 1.25
- = 20 km/h
4.A train travels at 30 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 37.5 km
- time = 1.25 h
- distance = speed × time = 30 × 1.25
- = 37.5 km
5.Ethan travels 25 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 20 km/h
- time = 1.25 h
- speed = distance ÷ time = 25 ÷ 1.25
- = 20 km/h
6.A train travels at 40 km/h for 15 minutes. How far does it travel?
Answer: 10 km
- time = 0.25 h
- distance = speed × time = 40 × 0.25
- = 10 km
7.Isla travels 150 km in 3 hours. What is the average speed in km/h?
Answer: 50 km/h
- time = 3 h
- speed = distance ÷ time = 150 ÷ 3
- = 50 km/h
8.A train travels at 100 km/h for 30 minutes. How far does it travel?
Answer: 50 km
- time = 0.5 h
- distance = speed × time = 100 × 0.5
- = 50 km
9.Ava travels 75 km in 45 minutes. What is the average speed in km/h?
Answer: 100 km/h
- time = 0.75 h
- speed = distance ÷ time = 75 ÷ 0.75
- = 100 km/h
10.Lucas travels 12.5 km in 30 minutes. What is the average speed in km/h?
Answer: 25 km/h

- = 25 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.
