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 1 hour 30 minutes. How far does it travel?
Answer: 45 km
- time = 1.5 h
- distance = speed × time = 30 × 1.5
- = 45 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 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
4.A train travels at 120 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 180 km
- time = 1.5 h
- distance = speed × time = 120 × 1.5
- = 180 km
5.Jack travels 75 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 1.25 h
- speed = distance ÷ time = 75 ÷ 1.25
- = 60 km/h
6.A train travels at 90 km/h for 1 hour 40 minutes. How far does it travel?
Answer: 150 km
- time = 1.6667 h
- distance = speed × time = 90 × 1.6667
- = 150 km
7.A car travels 22.5 km at an average speed of 30 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 22.5 ÷ 30
- = 0.75 h = 45 minutes
8.Olivia 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
9.Noah travels 67.5 km in 2 hours 15 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 2.25 h
- speed = distance ÷ time = 67.5 ÷ 2.25
- = 30 km/h
10.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
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.
