Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 400 km at an average speed of 100 km/h. How long does the trip take?
Answer: 4 hours
- time = distance ÷ speed = 400 ÷ 100
- = 4 h = 4 hours
2.A train travels at 35 km/h for 3 hours. How far does it travel?
Answer: 105 km
- time = 3 h
- distance = speed × time = 35 × 3
- = 105 km
3.A train travels at 80 km/h for 3 hours. How far does it travel?
Answer: 240 km
- time = 3 h
- distance = speed × time = 80 × 3
- = 240 km
4.A train travels at 110 km/h for 4 hours. How far does it travel?
Answer: 440 km
- time = 4 h
- distance = speed × time = 110 × 4
- = 440 km
5.A train travels at 35 km/h for 5 hours. How far does it travel?
Answer: 175 km
- time = 5 h
- distance = speed × time = 35 × 5
- = 175 km
6.A car travels 110 km at an average speed of 110 km/h. How long does the trip take?
Answer: 1 hour
- time = distance ÷ speed = 110 ÷ 110
- = 1 h = 1 hour
7.A car travels 420 km at an average speed of 105 km/h. How long does the trip take?
Answer: 4 hours
- time = distance ÷ speed = 420 ÷ 105
- = 4 h = 4 hours
8.A car travels 350 km at an average speed of 70 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 350 ÷ 70
- = 5 h = 5 hours
9.A car travels 500 km at an average speed of 100 km/h. How long does the trip take?
Answer: 5 hours
- time = distance ÷ speed = 500 ÷ 100
- = 5 h = 5 hours
10.Sienna travels 255 km in 3 hours. What is the average speed in km/h?
Answer: 85 km/h
- time = 3 h
- speed = distance ÷ time = 255 ÷ 3
- = 85 km/h
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.
