Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Mia travels 67.5 km in 45 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.75 h
- speed = distance ÷ time = 67.5 ÷ 0.75
- = 90 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 train travels at 90 km/h for 50 minutes. How far does it travel?
Answer: 75 km
- time = 0.8333 h
- distance = speed × time = 90 × 0.8333
- = 75 km
4.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
5.A car travels 80 km at an average speed of 120 km/h. How long does the trip take?
Answer: 40 minutes
- time = distance ÷ speed = 80 ÷ 120
- = 0.6667 h = 40 minutes
6.Ethan travels 50 km in 1 hour 40 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 1.6667 h
- speed = distance ÷ time = 50 ÷ 1.6667
- = 30 km/h
7.Ethan travels 112.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 1.25 h
- speed = distance ÷ time = 112.5 ÷ 1.25
- = 90 km/h
8.A train travels at 60 km/h for 2 hours 15 minutes. How far does it travel?
Answer: 135 km
- time = 2.25 h
- distance = speed × time = 60 × 2.25
- = 135 km
9.A car travels 40 km at an average speed of 60 km/h. How long does the trip take?
Answer: 40 minutes
- time = distance ÷ speed = 40 ÷ 60
- = 0.6667 h = 40 minutes
10.A car travels 20 km at an average speed of 30 km/h. How long does the trip take?
Answer: 40 minutes
- time = distance ÷ speed = 20 ÷ 30
- = 0.6667 h = 40 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.
