8th Grade Speed, Distance and Time Worksheet — Level 1 — Practice Set 3 — Answers
Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Jack travels 250 km in 5 hours. What is the average speed in km/h?
Answer: 50 km/h
- time = 5 h
- speed = distance ÷ time = 250 ÷ 5
- = 50 km/h
2.Tom 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
3.Harper travels 165 km in 3 hours. What is the average speed in km/h?
Answer: 55 km/h
- time = 3 h
- speed = distance ÷ time = 165 ÷ 3
- = 55 km/h
4.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
5.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
6.A train travels at 115 km/h for 1 hour. How far does it travel?
Answer: 115 km
- time = 1 h
- distance = speed × time = 115 × 1
- = 115 km
7.Zoe travels 130 km in 2 hours. What is the average speed in km/h?
Answer: 65 km/h
- time = 2 h
- speed = distance ÷ time = 130 ÷ 2
- = 65 km/h
8.A car travels 200 km at an average speed of 100 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 200 ÷ 100
- = 2 h = 2 hours
9.A car travels 600 km at an average speed of 120 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 600 ÷ 120
- = 5 h = 5 hours
10.A car travels 120 km at an average speed of 30 km/h. How long does the trip take?
Answer: 4 hours
- time = distance ÷ speed = 120 ÷ 30
- = 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.
