Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Ethan travels 10 km in 20 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 0.3333 h
- speed = distance ÷ time = 10 ÷ 0.3333
- = 30 km/h
2.A car travels 67.5 km at an average speed of 90 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 67.5 ÷ 90
- = 0.75 h = 45 minutes
3.A car travels 180 km at an average speed of 120 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 180 ÷ 120
- = 1.5 h = 1 hour 30 minutes
4.Mason 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
5.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
6.A train travels at 60 km/h for 45 minutes. How far does it travel?
Answer: 45 km
- time = 0.75 h
- distance = speed × time = 60 × 0.75
- = 45 km
7.A train travels at 90 km/h for 2 hours 15 minutes. How far does it travel?
Answer: 202.5 km
- time = 2.25 h
- distance = speed × time = 90 × 2.25
- = 202.5 km
8.A train travels at 60 km/h for 50 minutes. How far does it travel?
Answer: 50 km
- time = 0.8333 h
- distance = speed × time = 60 × 0.8333
- = 50 km
9.A train travels at 30 km/h for 1 hour 40 minutes. How far does it travel?
Answer: 50 km
- time = 1.6667 h
- distance = speed × time = 30 × 1.6667
- = 50 km
10.A car travels 45 km at an average speed of 30 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 45 ÷ 30
- = 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.
