Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Cooper travels 300 km in 3 hours. What is the average speed in km/h?
Answer: 100 km/h
- time = 3 h
- speed = distance ÷ time = 300 ÷ 3
- = 100 km/h
2.A car travels 112.5 km at an average speed of 75 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 112.5 ÷ 75
- = 1.5 h = 1 hour 30 minutes
3.A car travels 87.5 km at an average speed of 35 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 87.5 ÷ 35
- = 2.5 h = 2 hours 30 minutes
4.Tom travels 12.5 km in 30 minutes. What is the average speed in km/h?
Answer: 25 km/h
- time = 0.5 h
- speed = distance ÷ time = 12.5 ÷ 0.5
- = 25 km/h
5.A train travels at 20 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 25 km
- time = 1.25 h
- distance = speed × time = 20 × 1.25
- = 25 km
6.A car travels 31.25 km at an average speed of 25 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 31.25 ÷ 25
- = 1.25 h = 1 hour 15 minutes
7.A train travels at 90 km/h for 45 minutes. How far does it travel?
Answer: 67.5 km
- time = 0.75 h
- distance = speed × time = 90 × 0.75
- = 67.5 km
8.Hunter travels 67.5 km in 45 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.75 h
- speed = distance ÷ time = 67.5 ÷ 0.75
- = 90 km/h
9.A train travels at 110 km/h for 45 minutes. How far does it travel?
Answer: 82.5 km
- time = 0.75 h
- distance = speed × time = 110 × 0.75
- = 82.5 km
10.A train travels at 65 km/h for 15 minutes. How far does it travel?
Answer: 16.25 km
- time = 0.25 h
- distance = speed × time = 65 × 0.25
- = 16.25 km
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.
