Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 90 km at an average speed of 60 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 90 ÷ 60
- = 1.5 h = 1 hour 30 minutes
2.A train travels at 30 km/h for 40 minutes. How far does it travel?
Answer: 20 km
- time = 0.6667 h
- distance = speed × time = 30 × 0.6667
- = 20 km
3.A car travels 200 km at an average speed of 120 km/h. How long does the trip take?
Answer: 1 hour 40 minutes
- time = distance ÷ speed = 200 ÷ 120
- = 1.6667 h = 1 hour 40 minutes
4.A car travels 50 km at an average speed of 30 km/h. How long does the trip take?
Answer: 1 hour 40 minutes
- time = distance ÷ speed = 50 ÷ 30
- = 1.6667 h = 1 hour 40 minutes
5.A car travels 25 km at an average speed of 30 km/h. How long does the trip take?
Answer: 50 minutes
- time = distance ÷ speed = 25 ÷ 30
- = 0.8333 h = 50 minutes
6.Chloe travels 45 km in 45 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.75 h
- speed = distance ÷ time = 45 ÷ 0.75
- = 60 km/h
7.A train travels at 60 km/h for 40 minutes. How far does it travel?
Answer: 40 km
- time = 0.6667 h
- distance = speed × time = 60 × 0.6667
- = 40 km
8.A train travels at 90 km/h for 20 minutes. How far does it travel?
Answer: 30 km
- time = 0.3333 h
- distance = speed × time = 90 × 0.3333
- = 30 km
9.A train travels at 60 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 90 km
- time = 1.5 h
- distance = speed × time = 60 × 1.5
- = 90 km
10.Chloe travels 200 km in 1 hour 40 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 1.6667 h
- speed = distance ÷ time = 200 ÷ 1.6667
- = 120 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.
