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.Grace travels 50 km in 50 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.8333 h
- speed = distance ÷ time = 50 ÷ 0.8333
- = 60 km/h
3.A car travels 90 km at an average speed of 60 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 90 ÷ 60
- = 1.5 h = 1 hour 30 minutes
4.Hunter travels 100 km in 1 hour 40 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 1.6667 h
- speed = distance ÷ time = 100 ÷ 1.6667
- = 60 km/h
5.A train travels at 60 km/h for 20 minutes. How far does it travel?
Answer: 20 km
- time = 0.3333 h
- distance = speed × time = 60 × 0.3333
- = 20 km
6.Zoe travels 270 km in 2 hours 15 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 2.25 h
- speed = distance ÷ time = 270 ÷ 2.25
- = 120 km/h
7.A train travels at 120 km/h for 2 hours 15 minutes. How far does it travel?
Answer: 270 km
- time = 2.25 h
- distance = speed × time = 120 × 2.25
- = 270 km
8.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
9.A car travels 150 km at an average speed of 90 km/h. How long does the trip take?
Answer: 1 hour 40 minutes
- time = distance ÷ speed = 150 ÷ 90
- = 1.6667 h = 1 hour 40 minutes
10.A car travels 25 km at an average speed of 30 km/h. How long does the trip take?
Answer: 50 minutes
- time = distance ÷ speed = 25 ÷ 30
- = 0.8333 h = 50 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.
