Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Mason travels 27.5 km in 15 minutes. What is the average speed in km/h?
Answer: 110 km/h
- time = 0.25 h
- speed = distance ÷ time = 27.5 ÷ 0.25
- = 110 km/h
2.A train travels at 110 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 275 km
- time = 2.5 h
- distance = speed × time = 110 × 2.5
- = 275 km
3.A train travels at 115 km/h for 3 hours. How far does it travel?
Answer: 345 km
- time = 3 h
- distance = speed × time = 115 × 3
- = 345 km
4.Amelia travels 100 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 80 km/h
- time = 1.25 h
- speed = distance ÷ time = 100 ÷ 1.25
- = 80 km/h
5.A car travels 142.5 km at an average speed of 95 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 142.5 ÷ 95
- = 1.5 h = 1 hour 30 minutes
6.A car travels 18.75 km at an average speed of 25 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 18.75 ÷ 25
- = 0.75 h = 45 minutes
7.A car travels 10 km at an average speed of 20 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 10 ÷ 20
- = 0.5 h = 30 minutes
8.Amelia travels 87.5 km in 2 hours 30 minutes. What is the average speed in km/h?
Answer: 35 km/h
- time = 2.5 h
- speed = distance ÷ time = 87.5 ÷ 2.5
- = 35 km/h
9.A car travels 225 km at an average speed of 75 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 225 ÷ 75
- = 3 h = 3 hours
10.A car travels 35 km at an average speed of 70 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 35 ÷ 70
- = 0.5 h = 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.
