Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 250 km at an average speed of 100 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 250 ÷ 100
- = 2.5 h = 2 hours 30 minutes
2.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
3.Liam travels 30 km in 30 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.5 h
- speed = distance ÷ time = 30 ÷ 0.5
- = 60 km/h
4.Tom travels 90 km in 3 hours. What is the average speed in km/h?
Answer: 30 km/h
- time = 3 h
- speed = distance ÷ time = 90 ÷ 3
- = 30 km/h
5.Mia travels 56.25 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 45 km/h
- time = 1.25 h
- speed = distance ÷ time = 56.25 ÷ 1.25
- = 45 km/h
6.A car travels 212.5 km at an average speed of 85 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 212.5 ÷ 85
- = 2.5 h = 2 hours 30 minutes
7.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
8.A train travels at 110 km/h for 15 minutes. How far does it travel?
Answer: 27.5 km
- time = 0.25 h
- distance = speed × time = 110 × 0.25
- = 27.5 km
9.Cooper travels 7.5 km in 15 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.25 h
- speed = distance ÷ time = 7.5 ÷ 0.25
- = 30 km/h
10.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
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.
