Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Lucas travels 180 km in 3 hours. What is the average speed in km/h?
Answer: 60 km/h
- time = 3 h
- speed = distance ÷ time = 180 ÷ 3
- = 60 km/h
2.A train travels at 20 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 25 km
- time = 1.25 h
- distance = speed × time = 20 × 1.25
- = 25 km
3.A train travels at 100 km/h for 45 minutes. How far does it travel?
Answer: 75 km
- time = 0.75 h
- distance = speed × time = 100 × 0.75
- = 75 km
4.A car travels 172.5 km at an average speed of 115 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 172.5 ÷ 115
- = 1.5 h = 1 hour 30 minutes
5.A train travels at 85 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 212.5 km
- time = 2.5 h
- distance = speed × time = 85 × 2.5
- = 212.5 km
6.A train travels at 100 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 250 km
- time = 2.5 h
- distance = speed × time = 100 × 2.5
- = 250 km
7.A train travels at 30 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 75 km
- time = 2.5 h
- distance = speed × time = 30 × 2.5
- = 75 km
8.A car travels 225 km at an average speed of 90 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 225 ÷ 90
- = 2.5 h = 2 hours 30 minutes
9.A train travels at 75 km/h for 3 hours. How far does it travel?
Answer: 225 km
- time = 3 h
- distance = speed × time = 75 × 3
- = 225 km
10.A car travels 26.25 km at an average speed of 105 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 26.25 ÷ 105
- = 0.25 h = 15 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.
