Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 40 km at an average speed of 120 km/h. How long does the trip take?
Answer: 20 minutes
- time = distance ÷ speed = 40 ÷ 120
- = 0.3333 h = 20 minutes
2.A train travels at 120 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 150 km
- time = 1.25 h
- distance = speed × time = 120 × 1.25
- = 150 km
3.A train travels at 120 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 180 km
- time = 1.5 h
- distance = speed × time = 120 × 1.5
- = 180 km
4.A train travels at 60 km/h for 50 minutes. How far does it travel?
Answer: 50 km
- time = 0.8333 h
- distance = speed × time = 60 × 0.8333
- = 50 km
5.Cooper travels 75 km in 50 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.8333 h
- speed = distance ÷ time = 75 ÷ 0.8333
- = 90 km/h
6.A train travels at 90 km/h for 20 minutes. How far does it travel?
Answer: 30 km
- time = 0.3333 h
- distance = speed × time = 90 × 0.3333
- = 30 km
7.A car travels 135 km at an average speed of 60 km/h. How long does the trip take?
Answer: 2 hours 15 minutes
- time = distance ÷ speed = 135 ÷ 60
- = 2.25 h = 2 hours 15 minutes
8.A car travels 90 km at an average speed of 60 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 90 ÷ 60
- = 1.5 h = 1 hour 30 minutes
9.A train travels at 90 km/h for 45 minutes. How far does it travel?
Answer: 67.5 km
- time = 0.75 h
- distance = speed × time = 90 × 0.75
- = 67.5 km
10.Grace travels 45 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 1.5 h
- speed = distance ÷ time = 45 ÷ 1.5
- = 30 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.
