Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Isla travels 150 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 100 km/h
- time = 1.5 h
- speed = distance ÷ time = 150 ÷ 1.5
- = 100 km/h
2.Olivia travels 12.5 km in 15 minutes. What is the average speed in km/h?
Answer: 50 km/h
- time = 0.25 h
- speed = distance ÷ time = 12.5 ÷ 0.25
- = 50 km/h
3.A car travels 300 km at an average speed of 100 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 300 ÷ 100
- = 3 h = 3 hours
4.Max travels 112.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 1.25 h
- speed = distance ÷ time = 112.5 ÷ 1.25
- = 90 km/h
5.Kai travels 7.5 km in 15 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.25 h
- speed = distance ÷ time = 7.5 ÷ 0.25
- = 30 km/h
6.A train travels at 100 km/h for 30 minutes. How far does it travel?
Answer: 50 km
- time = 0.5 h
- distance = speed × time = 100 × 0.5
- = 50 km
7.A car travels 21.25 km at an average speed of 85 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 21.25 ÷ 85
- = 0.25 h = 15 minutes
8.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
9.A train travels at 40 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 50 km
- time = 1.25 h
- distance = speed × time = 40 × 1.25
- = 50 km
10.A train travels at 50 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 62.5 km
- time = 1.25 h
- distance = speed × time = 50 × 1.25
- = 62.5 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.
