Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 100 km at an average speed of 25 km/h. How long does the trip take?
Answer: 4 hours
- time = distance ÷ speed = 100 ÷ 25
- = 4 h = 4 hours
2.Olivia travels 180 km in 3 hours. What is the average speed in km/h?
Answer: 60 km/h
- time = 3 h
- speed = distance ÷ time = 180 ÷ 3
- = 60 km/h
3.A train travels at 85 km/h for 5 hours. How far does it travel?
Answer: 425 km
- time = 5 h
- distance = speed × time = 85 × 5
- = 425 km
4.A train travels at 110 km/h for 1 hour. How far does it travel?
Answer: 110 km
- time = 1 h
- distance = speed × time = 110 × 1
- = 110 km
5.Aisha travels 100 km in 2 hours. What is the average speed in km/h?
Answer: 50 km/h
- time = 2 h
- speed = distance ÷ time = 100 ÷ 2
- = 50 km/h
6.Grace travels 20 km in 1 hour. What is the average speed in km/h?
Answer: 20 km/h
- time = 1 h
- speed = distance ÷ time = 20 ÷ 1
- = 20 km/h
7.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
8.A train travels at 45 km/h for 2 hours. How far does it travel?
Answer: 90 km
- time = 2 h
- distance = speed × time = 45 × 2
- = 90 km
9.A train travels at 100 km/h for 2 hours. How far does it travel?
Answer: 200 km
- time = 2 h
- distance = speed × time = 100 × 2
- = 200 km
10.A car travels 60 km at an average speed of 30 km/h. How long does the trip take?
Answer: 2 hours
- time = distance ÷ speed = 60 ÷ 30
- = 2 h = 2 hours
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.
