Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 50 km at an average speed of 60 km/h. How long does the trip take?
Answer: 50 minutes
- time = distance ÷ speed = 50 ÷ 60
- = 0.8333 h = 50 minutes
2.Mia travels 30 km in 20 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.3333 h
- speed = distance ÷ time = 30 ÷ 0.3333
- = 90 km/h
3.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
- = 1.25 h = 1 hour 15 minutes
4.A car travels 90 km at an average speed of 120 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 90 ÷ 120
- = 0.75 h = 45 minutes
5.Chloe travels 150 km in 1 hour 40 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 1.6667 h
- speed = distance ÷ time = 150 ÷ 1.6667
- = 90 km/h
6.A car travels 270 km at an average speed of 120 km/h. How long does the trip take?
Answer: 2 hours 15 minutes
- time = distance ÷ speed = 270 ÷ 120
- = 2.25 h = 2 hours 15 minutes
7.A train travels at 30 km/h for 40 minutes. How far does it travel?
Answer: 20 km
- time = 0.6667 h
- distance = speed × time = 30 × 0.6667
- = 20 km
8.A train travels at 30 km/h for 2 hours 15 minutes. How far does it travel?
Answer: 67.5 km
- time = 2.25 h
- distance = speed × time = 30 × 2.25
- = 67.5 km
9.A train travels at 120 km/h for 1 hour 40 minutes. How far does it travel?
Answer: 200 km
- time = 1.6667 h
- distance = speed × time = 120 × 1.6667
- = 200 km
10.A car travels 45 km at an average speed of 60 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 45 ÷ 60
- = 0.75 h = 45 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.
