Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 25 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 31.25 km
- time = 1.25 h
- distance = speed × time = 25 × 1.25
- = 31.25 km
2.A train travels at 35 km/h for 15 minutes. How far does it travel?
Answer: 8.75 km
- time = 0.25 h
- distance = speed × time = 35 × 0.25
- = 8.75 km
3.A train travels at 40 km/h for 15 minutes. How far does it travel?
Answer: 10 km
- time = 0.25 h
- distance = speed × time = 40 × 0.25
- = 10 km
4.A car travels 8.75 km at an average speed of 35 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 8.75 ÷ 35
- = 0.25 h = 15 minutes
5.A train travels at 85 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 127.5 km
- time = 1.5 h
- distance = speed × time = 85 × 1.5
- = 127.5 km
6.A car travels 105 km at an average speed of 35 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 105 ÷ 35
- = 3 h = 3 hours
7.A car travels 330 km at an average speed of 110 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 330 ÷ 110
- = 3 h = 3 hours
8.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
9.A car travels 165 km at an average speed of 110 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 165 ÷ 110
- = 1.5 h = 1 hour 30 minutes
10.Ethan travels 13.75 km in 15 minutes. What is the average speed in km/h?
Answer: 55 km/h
- time = 0.25 h
- speed = distance ÷ time = 13.75 ÷ 0.25
- = 55 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.
