Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.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
2.Leo travels 8.75 km in 15 minutes. What is the average speed in km/h?
Answer: 35 km/h
- time = 0.25 h
- speed = distance ÷ time = 8.75 ÷ 0.25
- = 35 km/h
3.A train travels at 80 km/h for 15 minutes. How far does it travel?
Answer: 20 km
- time = 0.25 h
- distance = speed × time = 80 × 0.25
- = 20 km
4.A train travels at 20 km/h for 30 minutes. How far does it travel?
Answer: 10 km
- time = 0.5 h
- distance = speed × time = 20 × 0.5
- = 10 km
5.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
6.A train travels at 30 km/h for 15 minutes. How far does it travel?
Answer: 7.5 km
- time = 0.25 h
- distance = speed × time = 30 × 0.25
- = 7.5 km
7.Priya travels 105 km in 3 hours. What is the average speed in km/h?
Answer: 35 km/h
- time = 3 h
- speed = distance ÷ time = 105 ÷ 3
- = 35 km/h
8.A train travels at 20 km/h for 15 minutes. How far does it travel?
Answer: 5 km
- time = 0.25 h
- distance = speed × time = 20 × 0.25
- = 5 km
9.Tom travels 45 km in 30 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.5 h
- speed = distance ÷ time = 45 ÷ 0.5
- = 90 km/h
10.A train travels at 120 km/h for 45 minutes. How far does it travel?
Answer: 90 km
- time = 0.75 h
- distance = speed × time = 120 × 0.75
- = 90 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.
