Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 360 km at an average speed of 120 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 360 ÷ 120
- = 3 h = 3 hours
2.Emma travels 82.5 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 55 km/h
- time = 1.5 h
- speed = distance ÷ time = 82.5 ÷ 1.5
- = 55 km/h
3.A car travels 45 km at an average speed of 60 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 45 ÷ 60
- = 0.75 h = 45 minutes
4.A car travels 105 km at an average speed of 35 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 105 ÷ 35
- = 3 h = 3 hours
5.A train travels at 70 km/h for 45 minutes. How far does it travel?
Answer: 52.5 km
- time = 0.75 h
- distance = speed × time = 70 × 0.75
- = 52.5 km
6.A car travels 67.5 km at an average speed of 90 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 67.5 ÷ 90
- = 0.75 h = 45 minutes
7.A train travels at 80 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 200 km
- time = 2.5 h
- distance = speed × time = 80 × 2.5
- = 200 km
8.A train travels at 40 km/h for 15 minutes. How far does it travel?
Answer: 10 km
- time = 0.25 h
- distance = speed × time = 40 × 0.25
- = 10 km
9.A train travels at 105 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 157.5 km
- time = 1.5 h
- distance = speed × time = 105 × 1.5
- = 157.5 km
10.A car travels 90 km at an average speed of 120 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 90 ÷ 120
- = 0.75 h = 45 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.
