Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Amelia travels 35 km in 1 hour. What is the average speed in km/h?
Answer: 35 km/h
- time = 1 h
- speed = distance ÷ time = 35 ÷ 1
- = 35 km/h
2.Amelia travels 125 km in 5 hours. What is the average speed in km/h?
Answer: 25 km/h
- time = 5 h
- speed = distance ÷ time = 125 ÷ 5
- = 25 km/h
3.A train travels at 95 km/h for 5 hours. How far does it travel?
Answer: 475 km
- time = 5 h
- distance = speed × time = 95 × 5
- = 475 km
4.A car travels 190 km at an average speed of 95 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 190 ÷ 95
- = 2 h = 2 hours
5.A car travels 125 km at an average speed of 25 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 125 ÷ 25
- = 5 h = 5 hours
6.A train travels at 70 km/h for 2 hours. How far does it travel?
Answer: 140 km
- time = 2 h
- distance = speed × time = 70 × 2
- = 140 km
7.A train travels at 75 km/h for 1 hour. How far does it travel?
Answer: 75 km
- time = 1 h
- distance = speed × time = 75 × 1
- = 75 km
8.A train travels at 25 km/h for 4 hours. How far does it travel?
Answer: 100 km
- time = 4 h
- distance = speed × time = 25 × 4
- = 100 km
9.A train travels at 90 km/h for 3 hours. How far does it travel?
Answer: 270 km
- time = 3 h
- distance = speed × time = 90 × 3
- = 270 km
10.A train travels at 30 km/h for 2 hours. How far does it travel?
Answer: 60 km
- time = 2 h
- distance = speed × time = 30 × 2
- = 60 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.
