Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 100 km/h for 45 minutes. How far does it travel?
Answer: 75 km
- time = 0.75 h
- distance = speed × time = 100 × 0.75
- = 75 km
2.A car travels 18.75 km at an average speed of 25 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 18.75 ÷ 25
- = 0.75 h = 45 minutes
3.A train travels at 30 km/h for 15 minutes. How far does it travel?
Answer: 7.5 km
- time = 0.25 h
- distance = speed × time = 30 × 0.25
- = 7.5 km
4.A train travels at 40 km/h for 30 minutes. How far does it travel?
Answer: 20 km
- time = 0.5 h
- distance = speed × time = 40 × 0.5
- = 20 km
5.A train travels at 95 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 118.75 km
- time = 1.25 h
- distance = speed × time = 95 × 1.25
- = 118.75 km
6.Emma travels 67.5 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 45 km/h
- time = 1.5 h
- speed = distance ÷ time = 67.5 ÷ 1.5
- = 45 km/h
7.Sienna travels 180 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 1.5 h
- speed = distance ÷ time = 180 ÷ 1.5
- = 120 km/h
8.A train travels at 30 km/h for 30 minutes. How far does it travel?
Answer: 15 km
- time = 0.5 h
- distance = speed × time = 30 × 0.5
- = 15 km
9.A car travels 56.25 km at an average speed of 75 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 56.25 ÷ 75
- = 0.75 h = 45 minutes
10.A car travels 315 km at an average speed of 105 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 315 ÷ 105
- = 3 h = 3 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.
