Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 105 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 131.25 km
- time = 1.25 h
- distance = speed × time = 105 × 1.25
- = 131.25 km
2.Jack travels 52.5 km in 30 minutes. What is the average speed in km/h?
Answer: 105 km/h
- time = 0.5 h
- speed = distance ÷ time = 52.5 ÷ 0.5
- = 105 km/h
3.A car travels 30 km at an average speed of 40 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 30 ÷ 40
- = 0.75 h = 45 minutes
4.A car travels 22.5 km at an average speed of 45 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 22.5 ÷ 45
- = 0.5 h = 30 minutes
5.Ethan travels 52.5 km in 45 minutes. What is the average speed in km/h?
Answer: 70 km/h
- time = 0.75 h
- speed = distance ÷ time = 52.5 ÷ 0.75
- = 70 km/h
6.Zoe travels 22.5 km in 15 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.25 h
- speed = distance ÷ time = 22.5 ÷ 0.25
- = 90 km/h
7.Noah travels 26.25 km in 45 minutes. What is the average speed in km/h?
Answer: 35 km/h
- time = 0.75 h
- speed = distance ÷ time = 26.25 ÷ 0.75
- = 35 km/h
8.A train travels at 95 km/h for 3 hours. How far does it travel?
Answer: 285 km
- time = 3 h
- distance = speed × time = 95 × 3
- = 285 km
9.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
10.Noah travels 125 km in 2 hours 30 minutes. What is the average speed in km/h?
Answer: 50 km/h
- time = 2.5 h
- speed = distance ÷ time = 125 ÷ 2.5
- = 50 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.
