Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Jack travels 420 km in 4 hours. What is the average speed in km/h?
Answer: 105 km/h
- time = 4 h
- speed = distance ÷ time = 420 ÷ 4
- = 105 km/h
2.A car travels 80 km at an average speed of 40 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 80 ÷ 40
- = 2 h = 2 hours
3.A car travels 360 km at an average speed of 120 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 360 ÷ 120
- = 3 h = 3 hours
4.A train travels at 70 km/h for 4 hours. How far does it travel?
Answer: 280 km
- time = 4 h
- distance = speed × time = 70 × 4
- = 280 km
5.A car travels 260 km at an average speed of 65 km/h. How long does the trip take?
Answer: 4 hours
- time = distance ÷ speed = 260 ÷ 65
- = 4 h = 4 hours
6.A train travels at 120 km/h for 1 hour. How far does it travel?
Answer: 120 km
- time = 1 h
- distance = speed × time = 120 × 1
- = 120 km
7.A train travels at 45 km/h for 3 hours. How far does it travel?
Answer: 135 km
- time = 3 h
- distance = speed × time = 45 × 3
- = 135 km
8.A train travels at 40 km/h for 1 hour. How far does it travel?
Answer: 40 km
- time = 1 h
- distance = speed × time = 40 × 1
- = 40 km
9.A train travels at 100 km/h for 2 hours. How far does it travel?
Answer: 200 km
- time = 2 h
- distance = speed × time = 100 × 2
- = 200 km
10.Ethan travels 85 km in 1 hour. What is the average speed in km/h?
Answer: 85 km/h
- time = 1 h
- speed = distance ÷ time = 85 ÷ 1
- = 85 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.
