Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Aisha travels 20 km in 40 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.6667 h
- speed = distance ÷ time = 20 ÷ 0.6667
- = 30 km/h
2.A car travels 270 km at an average speed of 120 km/h. How long does the trip take?
Answer: 2 hours 15 minutes
- time = distance ÷ speed = 270 ÷ 120
- = 2.25 h = 2 hours 15 minutes
3.A train travels at 30 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 37.5 km
- time = 1.25 h
- distance = speed × time = 30 × 1.25
- = 37.5 km
4.Tom 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
5.A train travels at 60 km/h for 2 hours 15 minutes. How far does it travel?
Answer: 135 km
- time = 2.25 h
- distance = speed × time = 60 × 2.25
- = 135 km
6.Mia travels 50 km in 50 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.8333 h
- speed = distance ÷ time = 50 ÷ 0.8333
- = 60 km/h
7.A train travels at 60 km/h for 45 minutes. How far does it travel?
Answer: 45 km
- time = 0.75 h
- distance = speed × time = 60 × 0.75
- = 45 km
8.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
9.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
10.Oliver travels 270 km in 2 hours 15 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 2.25 h
- speed = distance ÷ time = 270 ÷ 2.25
- = 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.
