Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 120 km/h for 30 minutes. How far does it travel?
Answer: 60 km
- time = 0.5 h
- distance = speed × time = 120 × 0.5
- = 60 km
2.A car travels 25 km at an average speed of 20 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 25 ÷ 20
- = 1.25 h = 1 hour 15 minutes
3.A train travels at 100 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 125 km
- time = 1.25 h
- distance = speed × time = 100 × 1.25
- = 125 km
4.A train travels at 115 km/h for 3 hours. How far does it travel?
Answer: 345 km
- time = 3 h
- distance = speed × time = 115 × 3
- = 345 km
5.A car travels 41.25 km at an average speed of 55 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 41.25 ÷ 55
- = 0.75 h = 45 minutes
6.Chloe travels 17.5 km in 15 minutes. What is the average speed in km/h?
Answer: 70 km/h
- time = 0.25 h
- speed = distance ÷ time = 17.5 ÷ 0.25
- = 70 km/h
7.A train travels at 80 km/h for 45 minutes. How far does it travel?
Answer: 60 km
- time = 0.75 h
- distance = speed × time = 80 × 0.75
- = 60 km
8.A car travels 20 km at an average speed of 40 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 20 ÷ 40
- = 0.5 h = 30 minutes
9.A train travels at 85 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 106.25 km
- time = 1.25 h
- distance = speed × time = 85 × 1.25
- = 106.25 km
10.Ava travels 157.5 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 105 km/h
- time = 1.5 h
- speed = distance ÷ time = 157.5 ÷ 1.5
- = 105 km/h
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.
