Year 8 Speed, Distance and Time Worksheet — Level 1 — Practice Set 4 — Answers
Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Sienna 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
2.Ava travels 240 km in 3 hours. What is the average speed in km/h?
Answer: 80 km/h
- time = 3 h
- speed = distance ÷ time = 240 ÷ 3
- = 80 km/h
3.Cooper 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
4.Tom travels 80 km in 4 hours. What is the average speed in km/h?
Answer: 20 km/h

- speed = distance ÷ time = 80 ÷ 4
- = 20 km/h
5.Noah travels 345 km in 3 hours. What is the average speed in km/h?
Answer: 115 km/h
- time = 3 h
- speed = distance ÷ time = 345 ÷ 3
- = 115 km/h
6.A train travels at 35 km/h for 1 hour. How far does it travel?
Answer: 35 km
- time = 1 h
- distance = speed × time = 35 × 1
- = 35 km
7.A car travels 120 km at an average speed of 120 km/h. How long does the trip take?
Answer: 1 hour
- time = distance ÷ speed = 120 ÷ 120
- = 1 h = 1 hour
8.Ava travels 110 km in 1 hour. What is the average speed in km/h?
Answer: 110 km/h
- time = 1 h
- speed = distance ÷ time = 110 ÷ 1
- = 110 km/h
9.A car travels 475 km at an average speed of 95 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 475 ÷ 95
- = 5 h = 5 hours
10.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
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.
