Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 67.5 km at an average speed of 90 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 67.5 ÷ 90
- = 0.75 h = 45 minutes
2.A train travels at 60 km/h for 2 hours 15 minutes. How far does it travel?
Answer: 135 km
- time = 2.25 h
- distance = speed × time = 60 × 2.25
- = 135 km
3.Tom travels 80 km in 40 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.6667 h
- speed = distance ÷ time = 80 ÷ 0.6667
- = 120 km/h
4.A train travels at 120 km/h for 40 minutes. How far does it travel?
Answer: 80 km
- time = 0.6667 h
- distance = speed × time = 120 × 0.6667
- = 80 km
5.Archie travels 20 km in 40 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.6667 h
- speed = distance ÷ time = 20 ÷ 0.6667
- = 30 km/h
6.A train travels at 120 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 180 km
- time = 1.5 h
- distance = speed × time = 120 × 1.5
- = 180 km
7.Max travels 20 km in 20 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.3333 h
- speed = distance ÷ time = 20 ÷ 0.3333
- = 60 km/h
8.Mason travels 150 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 1.25 h
- speed = distance ÷ time = 150 ÷ 1.25
- = 120 km/h
9.A car travels 270 km at an average speed of 120 km/h. How long does the trip take?
Answer: 2 hours 15 minutes
- time = distance ÷ speed = 270 ÷ 120
- = 2.25 h = 2 hours 15 minutes
10.A train travels at 90 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 112.5 km
- time = 1.25 h
- distance = speed × time = 90 × 1.25
- = 112.5 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.
