Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 50 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 75 km
- time = 1.5 h
- distance = speed × time = 50 × 1.5
- = 75 km
2.Noah travels 15 km in 45 minutes. What is the average speed in km/h?
Answer: 20 km/h
- time = 0.75 h
- speed = distance ÷ time = 15 ÷ 0.75
- = 20 km/h
3.A car travels 30 km at an average speed of 60 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 30 ÷ 60
- = 0.5 h = 30 minutes
4.A train travels at 95 km/h for 3 hours. How far does it travel?
Answer: 285 km
- time = 3 h
- distance = speed × time = 95 × 3
- = 285 km
5.Ava travels 7.5 km in 15 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.25 h
- speed = distance ÷ time = 7.5 ÷ 0.25
- = 30 km/h
6.A car travels 57.5 km at an average speed of 115 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 57.5 ÷ 115
- = 0.5 h = 30 minutes
7.A car travels 106.25 km at an average speed of 85 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 106.25 ÷ 85
- = 1.25 h = 1 hour 15 minutes
8.Hunter travels 125 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 100 km/h
- time = 1.25 h
- speed = distance ÷ time = 125 ÷ 1.25
- = 100 km/h
9.Mia travels 57.5 km in 30 minutes. What is the average speed in km/h?
Answer: 115 km/h
- time = 0.5 h
- speed = distance ÷ time = 57.5 ÷ 0.5
- = 115 km/h
10.A car travels 150 km at an average speed of 120 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 150 ÷ 120

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.
