Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 65 km/h for 3 hours. How far does it travel?
Answer: 195 km
- time = 3 h
- distance = speed × time = 65 × 3
- = 195 km
2.A train travels at 50 km/h for 15 minutes. How far does it travel?
Answer: 12.5 km
- time = 0.25 h
- distance = speed × time = 50 × 0.25
- = 12.5 km
3.A train travels at 90 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 112.5 km
- time = 1.25 h
- distance = speed × time = 90 × 1.25
- = 112.5 km
4.A car travels 32.5 km at an average speed of 65 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 32.5 ÷ 65
- = 0.5 h = 30 minutes
5.A train travels at 45 km/h for 30 minutes. How far does it travel?
Answer: 22.5 km
- time = 0.5 h
- distance = speed × time = 45 × 0.5
- = 22.5 km
6.Grace travels 262.5 km in 2 hours 30 minutes. What is the average speed in km/h?
Answer: 105 km/h
- time = 2.5 h
- speed = distance ÷ time = 262.5 ÷ 2.5
- = 105 km/h
7.A train travels at 40 km/h for 45 minutes. How far does it travel?
Answer: 30 km
- time = 0.75 h
- distance = speed × time = 40 × 0.75
- = 30 km
8.A train travels at 95 km/h for 30 minutes. How far does it travel?
Answer: 47.5 km
- time = 0.5 h
- distance = speed × time = 95 × 0.5
- = 47.5 km
9.Aisha travels 137.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 110 km/h
- time = 1.25 h
- speed = distance ÷ time = 137.5 ÷ 1.25
- = 110 km/h
10.A car travels 15 km at an average speed of 60 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 15 ÷ 60
- = 0.25 h = 15 minutes
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.
