Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 120 km/h for 50 minutes. How far does it travel?
Answer: 100 km
- time = 0.8333 h
- distance = speed × time = 120 × 0.8333
- = 100 km
2.A train travels at 90 km/h for 40 minutes. How far does it travel?
Answer: 60 km
- time = 0.6667 h
- distance = speed × time = 90 × 0.6667
- = 60 km
3.A train travels at 120 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 150 km
- time = 1.25 h
- distance = speed × time = 120 × 1.25
- = 150 km
4.A train travels at 90 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 112.5 km
- time = 1.25 h
- distance = speed × time = 90 × 1.25
- = 112.5 km
5.Amelia travels 67.5 km in 45 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.75 h
- speed = distance ÷ time = 67.5 ÷ 0.75
- = 90 km/h
6.Isla travels 37.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 1.25 h
- speed = distance ÷ time = 37.5 ÷ 1.25
- = 30 km/h
7.A train travels at 120 km/h for 40 minutes. How far does it travel?
Answer: 80 km
- time = 0.6667 h
- distance = speed × time = 120 × 0.6667
- = 80 km
8.A car travels 50 km at an average speed of 60 km/h. How long does the trip take?
Answer: 50 minutes
- time = distance ÷ speed = 50 ÷ 60
- = 0.8333 h = 50 minutes
9.A car travels 45 km at an average speed of 30 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 45 ÷ 30
- = 1.5 h = 1 hour 30 minutes
10.A car travels 135 km at an average speed of 60 km/h. How long does the trip take?
Answer: 2 hours 15 minutes
- time = distance ÷ speed = 135 ÷ 60
- = 2.25 h = 2 hours 15 minutes
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.
