Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 50 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 75 km
- time = 1.5 h
- distance = speed × time = 50 × 1.5
- = 75 km
2.A car travels 82.5 km at an average speed of 55 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 82.5 ÷ 55
- = 1.5 h = 1 hour 30 minutes
3.Ethan travels 37.5 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 25 km/h
- time = 1.5 h
- speed = distance ÷ time = 37.5 ÷ 1.5
- = 25 km/h
4.Aisha travels 15 km in 15 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.25 h
- speed = distance ÷ time = 15 ÷ 0.25
- = 60 km/h
5.Liam travels 165 km in 3 hours. What is the average speed in km/h?
Answer: 55 km/h
- time = 3 h
- speed = distance ÷ time = 165 ÷ 3
- = 55 km/h
6.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
7.A train travels at 90 km/h for 30 minutes. How far does it travel?
Answer: 45 km
- time = 0.5 h
- distance = speed × time = 90 × 0.5
- = 45 km
8.A train travels at 120 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 150 km
- time = 1.25 h
- distance = speed × time = 120 × 1.25
- = 150 km
9.A train travels at 75 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 112.5 km
- time = 1.5 h
- distance = speed × time = 75 × 1.5
- = 112.5 km
10.A car travels 37.5 km at an average speed of 75 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 37.5 ÷ 75
- = 0.5 h = 30 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.
