Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Oliver 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
2.A train travels at 100 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 150 km
- time = 1.5 h
- distance = speed × time = 100 × 1.5
- = 150 km
3.A car travels 127.5 km at an average speed of 85 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 127.5 ÷ 85
- = 1.5 h = 1 hour 30 minutes
4.A car travels 300 km at an average speed of 100 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 300 ÷ 100
- = 3 h = 3 hours
5.A train travels at 40 km/h for 30 minutes. How far does it travel?
Answer: 20 km
- time = 0.5 h
- distance = speed × time = 40 × 0.5
- = 20 km
6.A car travels 157.5 km at an average speed of 105 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 157.5 ÷ 105
- = 1.5 h = 1 hour 30 minutes
7.A train travels at 25 km/h for 30 minutes. How far does it travel?
Answer: 12.5 km
- time = 0.5 h
- distance = speed × time = 25 × 0.5
- = 12.5 km
8.A car travels 143.75 km at an average speed of 115 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 143.75 ÷ 115
- = 1.25 h = 1 hour 15 minutes
9.A car travels 50 km at an average speed of 20 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 50 ÷ 20
- = 2.5 h = 2 hours 30 minutes
10.A car travels 78.75 km at an average speed of 105 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 78.75 ÷ 105
- = 0.75 h = 45 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.
