Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Hunter travels 90 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 1.5 h
- speed = distance ÷ time = 90 ÷ 1.5
- = 60 km/h
2.Layla travels 22.5 km in 30 minutes. What is the average speed in km/h?
Answer: 45 km/h
- time = 0.5 h
- speed = distance ÷ time = 22.5 ÷ 0.5
- = 45 km/h
3.Olivia travels 262.5 km in 2 hours 30 minutes. What is the average speed in km/h?
Answer: 105 km/h
- time = 2.5 h
- speed = distance ÷ time = 262.5 ÷ 2.5
- = 105 km/h
4.A train travels at 100 km/h for 3 hours. How far does it travel?
Answer: 300 km
- time = 3 h
- distance = speed × time = 100 × 3
- = 300 km
5.A car travels 150 km at an average speed of 120 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 150 ÷ 120
- = 1.25 h = 1 hour 15 minutes
6.A car travels 25 km at an average speed of 50 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 25 ÷ 50
- = 0.5 h = 30 minutes
7.A car travels 15 km at an average speed of 60 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 15 ÷ 60
- = 0.25 h = 15 minutes
8.A car travels 6.25 km at an average speed of 25 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 6.25 ÷ 25
- = 0.25 h = 15 minutes
9.A train travels at 30 km/h for 3 hours. How far does it travel?
Answer: 90 km
- time = 3 h
- distance = speed × time = 30 × 3
- = 90 km
10.A train travels at 80 km/h for 30 minutes. How far does it travel?
Answer: 40 km
- time = 0.5 h
- distance = speed × time = 80 × 0.5
- = 40 km
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.
