Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 270 km at an average speed of 90 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 270 ÷ 90
- = 3 h = 3 hours
2.A train travels at 25 km/h for 45 minutes. How far does it travel?
Answer: 18.75 km
- time = 0.75 h
- distance = speed × time = 25 × 0.75
- = 18.75 km
3.Ethan travels 18.75 km in 15 minutes. What is the average speed in km/h?
Answer: 75 km/h
- time = 0.25 h
- speed = distance ÷ time = 18.75 ÷ 0.25
- = 75 km/h
4.A car travels 62.5 km at an average speed of 25 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 62.5 ÷ 25
- = 2.5 h = 2 hours 30 minutes
5.A car travels 97.5 km at an average speed of 65 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 97.5 ÷ 65
- = 1.5 h = 1 hour 30 minutes
6.Lucas 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
7.Isla travels 90 km in 45 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.75 h
- speed = distance ÷ time = 90 ÷ 0.75
- = 120 km/h
8.A train travels at 70 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 175 km
- time = 2.5 h

- = 175 km
9.A car travels 62.5 km at an average speed of 50 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 62.5 ÷ 50

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.
