Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 50 km/h for 4 hours. How far does it travel?
Answer: 200 km
- time = 4 h
- distance = speed × time = 50 × 4
- = 200 km
2.A train travels at 55 km/h for 2 hours. How far does it travel?
Answer: 110 km
- time = 2 h
- distance = speed × time = 55 × 2
- = 110 km
3.Grace travels 35 km in 1 hour. What is the average speed in km/h?
Answer: 35 km/h
- time = 1 h
- speed = distance ÷ time = 35 ÷ 1
- = 35 km/h
4.Jack travels 210 km in 3 hours. What is the average speed in km/h?
Answer: 70 km/h
- time = 3 h
- speed = distance ÷ time = 210 ÷ 3
- = 70 km/h
5.A car travels 230 km at an average speed of 115 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 230 ÷ 115
- = 2 h = 2 hours
6.A car travels 75 km at an average speed of 75 km/h. How long does the trip take?
Answer: 1 hour
- time = distance ÷ speed = 75 ÷ 75
- = 1 h = 1 hour
7.A car travels 55 km at an average speed of 55 km/h. How long does the trip take?
Answer: 1 hour
- time = distance ÷ speed = 55 ÷ 55
- = 1 h = 1 hour
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.Cooper travels 475 km in 5 hours. What is the average speed in km/h?
Answer: 95 km/h
- time = 5 h
- speed = distance ÷ time = 475 ÷ 5
- = 95 km/h
10.Noah travels 440 km in 4 hours. What is the average speed in km/h?
Answer: 110 km/h
- time = 4 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.
