Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Chloe travels 90 km in 45 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.75 h
- speed = distance ÷ time = 90 ÷ 0.75
- = 120 km/h
2.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
3.Ethan travels 90 km in 45 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.75 h
- speed = distance ÷ time = 90 ÷ 0.75
- = 120 km/h
4.A car travels 43.75 km at an average speed of 35 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 43.75 ÷ 35
- = 1.25 h = 1 hour 15 minutes
5.A car travels 150 km at an average speed of 50 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 150 ÷ 50
- = 3 h = 3 hours
6.A car travels 35 km at an average speed of 70 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 35 ÷ 70
- = 0.5 h = 30 minutes
7.A train travels at 110 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 165 km
- time = 1.5 h
- distance = speed × time = 110 × 1.5
- = 165 km
8.Kai travels 90 km in 45 minutes. What is the average speed in km/h?
Answer: 120 km/h
- time = 0.75 h
- speed = distance ÷ time = 90 ÷ 0.75
- = 120 km/h
9.A train travels at 45 km/h for 30 minutes. How far does it travel?
Answer: 22.5 km
- time = 0.5 h
- distance = speed × time = 45 × 0.5
- = 22.5 km
10.A car travels 105 km at an average speed of 70 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 105 ÷ 70
- = 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.
