Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Noah travels 255 km in 3 hours. What is the average speed in km/h?
Answer: 85 km/h
- time = 3 h
- speed = distance ÷ time = 255 ÷ 3
- = 85 km/h
2.A train travels at 120 km/h for 5 hours. How far does it travel?
Answer: 600 km
- time = 5 h
- distance = speed × time = 120 × 5
- = 600 km
3.A train travels at 40 km/h for 5 hours. How far does it travel?
Answer: 200 km
- time = 5 h
- distance = speed × time = 40 × 5
- = 200 km
4.Tom travels 425 km in 5 hours. What is the average speed in km/h?
Answer: 85 km/h
- time = 5 h
- speed = distance ÷ time = 425 ÷ 5
- = 85 km/h
5.A car travels 400 km at an average speed of 100 km/h. How long does the trip take?
Answer: 4 hours
- time = distance ÷ speed = 400 ÷ 100
- = 4 h = 4 hours
6.A train travels at 90 km/h for 4 hours. How far does it travel?
Answer: 360 km
- time = 4 h
- distance = speed × time = 90 × 4
- = 360 km
7.A train travels at 70 km/h for 3 hours. How far does it travel?
Answer: 210 km
- time = 3 h
- distance = speed × time = 70 × 3
- = 210 km
8.Oliver travels 40 km in 2 hours. What is the average speed in km/h?
Answer: 20 km/h
- time = 2 h
- speed = distance ÷ time = 40 ÷ 2
- = 20 km/h
9.A car travels 100 km at an average speed of 25 km/h. How long does the trip take?
Answer: 4 hours
- time = distance ÷ speed = 100 ÷ 25
- = 4 h = 4 hours
10.A car travels 500 km at an average speed of 100 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 500 ÷ 100
- = 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.
