Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Emma travels 60 km in 1 hour. What is the average speed in km/h?
Answer: 60 km/h
- time = 1 h
- speed = distance ÷ time = 60 ÷ 1
- = 60 km/h
2.A car travels 70 km at an average speed of 70 km/h. How long does the trip take?
Answer: 1 hour
- time = distance ÷ speed = 70 ÷ 70
- = 1 h = 1 hour
3.A train travels at 30 km/h for 4 hours. How far does it travel?
Answer: 120 km
- time = 4 h
- distance = speed × time = 30 × 4
- = 120 km
4.A train travels at 25 km/h for 4 hours. How far does it travel?
Answer: 100 km
- time = 4 h
- distance = speed × time = 25 × 4
- = 100 km
5.A train travels at 55 km/h for 5 hours. How far does it travel?
Answer: 275 km
- time = 5 h
- distance = speed × time = 55 × 5
- = 275 km
6.A train travels at 115 km/h for 4 hours. How far does it travel?
Answer: 460 km
- time = 4 h
- distance = speed × time = 115 × 4
- = 460 km
7.A train travels at 110 km/h for 5 hours. How far does it travel?
Answer: 550 km
- time = 5 h
- distance = speed × time = 110 × 5
- = 550 km
8.Harper travels 90 km in 2 hours. What is the average speed in km/h?
Answer: 45 km/h
- time = 2 h
- speed = distance ÷ time = 90 ÷ 2
- = 45 km/h
9.A car travels 140 km at an average speed of 70 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 140 ÷ 70
- = 2 h = 2 hours
10.A car travels 225 km at an average speed of 45 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 225 ÷ 45
- = 5 h = 5 hours
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.
