Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Oliver travels 300 km in 2 hours 30 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 2.5 h
- speed = distance ÷ time = 300 ÷ 2.5
- = 120 km/h
2.A train travels at 75 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 112.5 km
- time = 1.5 h
- distance = speed × time = 75 × 1.5
- = 112.5 km
3.A train travels at 115 km/h for 3 hours. How far does it travel?
Answer: 345 km
- time = 3 h
- distance = speed × time = 115 × 3
- = 345 km
4.A train travels at 45 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 112.5 km
- time = 2.5 h
- distance = speed × time = 45 × 2.5
- = 112.5 km
5.A train travels at 75 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 187.5 km
- time = 2.5 h
- distance = speed × time = 75 × 2.5
- = 187.5 km
6.A car travels 275 km at an average speed of 110 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 275 ÷ 110
- = 2.5 h = 2 hours 30 minutes
7.A car travels 86.25 km at an average speed of 115 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 86.25 ÷ 115
- = 0.75 h = 45 minutes
8.A car travels 87.5 km at an average speed of 70 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 87.5 ÷ 70
- = 1.25 h = 1 hour 15 minutes
9.A car travels 105 km at an average speed of 70 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 105 ÷ 70
- = 1.5 h = 1 hour 30 minutes
10.Ava travels 5 km in 15 minutes. What is the average speed in km/h?
Answer: 20 km/h
- time = 0.25 h
- speed = distance ÷ time = 5 ÷ 0.25
- = 20 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.
