Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 35 km at an average speed of 70 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 35 ÷ 70
- = 0.5 h = 30 minutes
2.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
3.A train travels at 110 km/h for 45 minutes. How far does it travel?
Answer: 82.5 km
- time = 0.75 h
- distance = speed × time = 110 × 0.75
- = 82.5 km
4.A train travels at 120 km/h for 3 hours. How far does it travel?
Answer: 360 km
- time = 3 h
- distance = speed × time = 120 × 3
- = 360 km
5.A car travels 75 km at an average speed of 60 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 75 ÷ 60
- = 1.25 h = 1 hour 15 minutes
6.A car travels 12.5 km at an average speed of 25 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 12.5 ÷ 25
- = 0.5 h = 30 minutes
7.A car travels 81.25 km at an average speed of 65 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 81.25 ÷ 65
- = 1.25 h = 1 hour 15 minutes
8.A train travels at 90 km/h for 30 minutes. How far does it travel?
Answer: 45 km
- time = 0.5 h
- distance = speed × time = 90 × 0.5
- = 45 km
9.A train travels at 40 km/h for 3 hours. How far does it travel?
Answer: 120 km
- time = 3 h
- distance = speed × time = 40 × 3
- = 120 km
10.Cooper travels 137.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 110 km/h
- time = 1.25 h
- speed = distance ÷ time = 137.5 ÷ 1.25
- = 110 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.
