Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 55 km/h for 4 hours. How far does it travel?
Answer: 220 km
- time = 4 h
- distance = speed × time = 55 × 4
- = 220 km
2.Jack travels 60 km in 3 hours. What is the average speed in km/h?
Answer: 20 km/h
- time = 3 h
- speed = distance ÷ time = 60 ÷ 3
- = 20 km/h
3.Aisha travels 100 km in 4 hours. What is the average speed in km/h?
Answer: 25 km/h
- time = 4 h
- speed = distance ÷ time = 100 ÷ 4
- = 25 km/h
4.A train travels at 55 km/h for 3 hours. How far does it travel?
Answer: 165 km
- time = 3 h
- distance = speed × time = 55 × 3
- = 165 km
5.A train travels at 20 km/h for 4 hours. How far does it travel?
Answer: 80 km
- time = 4 h
- distance = speed × time = 20 × 4
- = 80 km
6.A train travels at 50 km/h for 2 hours. How far does it travel?
Answer: 100 km
- time = 2 h
- distance = speed × time = 50 × 2
- = 100 km
7.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
8.A car travels 170 km at an average speed of 85 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 170 ÷ 85
- = 2 h = 2 hours
9.A car travels 150 km at an average speed of 30 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 150 ÷ 30
- = 5 h = 5 hours
10.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
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.
