Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 30 km/h for 50 minutes. How far does it travel?
Answer: 25 km
- time = 0.8333 h
- distance = speed × time = 30 × 0.8333
- = 25 km
2.A train travels at 120 km/h for 45 minutes. How far does it travel?
Answer: 90 km
- time = 0.75 h
- distance = speed × time = 120 × 0.75
- = 90 km
3.A train travels at 60 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 75 km
- time = 1.25 h
- distance = speed × time = 60 × 1.25
- = 75 km
4.A car travels 60 km at an average speed of 90 km/h. How long does the trip take?
Answer: 40 minutes
- time = distance ÷ speed = 60 ÷ 90
- = 0.6667 h = 40 minutes
5.Ruby 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
6.A car travels 40 km at an average speed of 120 km/h. How long does the trip take?
Answer: 20 minutes
- time = distance ÷ speed = 40 ÷ 120
- = 0.3333 h = 20 minutes
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 train travels at 60 km/h for 40 minutes. How far does it travel?
Answer: 40 km
- time = 0.6667 h
- distance = speed × time = 60 × 0.6667
- = 40 km
9.Ava travels 20 km in 40 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.6667 h
- speed = distance ÷ time = 20 ÷ 0.6667
- = 30 km/h
10.A car travels 135 km at an average speed of 90 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 135 ÷ 90
- = 1.5 h = 1 hour 30 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.
