Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 90 km at an average speed of 30 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 90 ÷ 30
- = 3 h = 3 hours
2.A train travels at 105 km/h for 30 minutes. How far does it travel?
Answer: 52.5 km
- time = 0.5 h
- distance = speed × time = 105 × 0.5
- = 52.5 km
3.A car travels 345 km at an average speed of 115 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 345 ÷ 115
- = 3 h = 3 hours
4.A train travels at 95 km/h for 45 minutes. How far does it travel?
Answer: 71.25 km
- time = 0.75 h
- distance = speed × time = 95 × 0.75
- = 71.25 km
5.A car travels 17.5 km at an average speed of 35 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 17.5 ÷ 35
- = 0.5 h = 30 minutes
6.A train travels at 115 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 172.5 km
- time = 1.5 h
- distance = speed × time = 115 × 1.5
- = 172.5 km
7.Amelia travels 60 km in 30 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.5 h
- speed = distance ÷ time = 60 ÷ 0.5
- = 120 km/h
8.Leo travels 13.75 km in 15 minutes. What is the average speed in km/h?
Answer: 55 km/h
- time = 0.25 h
- speed = distance ÷ time = 13.75 ÷ 0.25
- = 55 km/h
9.A train travels at 55 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 137.5 km
- time = 2.5 h
- distance = speed × time = 55 × 2.5
- = 137.5 km
10.A car travels 52.5 km at an average speed of 70 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 52.5 ÷ 70
- = 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.
