Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 150 km at an average speed of 60 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 150 ÷ 60
- = 2.5 h = 2 hours 30 minutes
2.Kai travels 20 km in 30 minutes. What is the average speed in km/h?
Answer: 40 km/h
- time = 0.5 h
- speed = distance ÷ time = 20 ÷ 0.5
- = 40 km/h
3.A car travels 41.25 km at an average speed of 55 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 41.25 ÷ 55
- = 0.75 h = 45 minutes
4.A train travels at 90 km/h for 15 minutes. How far does it travel?
Answer: 22.5 km
- time = 0.25 h
- distance = speed × time = 90 × 0.25
- = 22.5 km
5.A car travels 17.5 km at an average speed of 70 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 17.5 ÷ 70
- = 0.25 h = 15 minutes
6.A train travels at 55 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 68.75 km
- time = 1.25 h
- distance = speed × time = 55 × 1.25
- = 68.75 km
7.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
8.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
9.Chloe travels 16.25 km in 15 minutes. What is the average speed in km/h?
Answer: 65 km/h
- time = 0.25 h
- speed = distance ÷ time = 16.25 ÷ 0.25
- = 65 km/h
10.A car travels 75 km at an average speed of 30 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 75 ÷ 30
- = 2.5 h = 2 hours 30 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.
