Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Kai travels 45 km in 45 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 0.75 h
- speed = distance ÷ time = 45 ÷ 0.75
- = 60 km/h
2.A train travels at 70 km/h for 30 minutes. How far does it travel?
Answer: 35 km
- time = 0.5 h
- distance = speed × time = 70 × 0.5
- = 35 km
3.A car travels 75 km at an average speed of 30 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 75 ÷ 30
- = 2.5 h = 2 hours 30 minutes
4.A car travels 187.5 km at an average speed of 75 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 187.5 ÷ 75
- = 2.5 h = 2 hours 30 minutes
5.Kai travels 150 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 100 km/h
- time = 1.5 h
- speed = distance ÷ time = 150 ÷ 1.5
- = 100 km/h
6.Lucas travels 71.25 km in 45 minutes. What is the average speed in km/h?
Answer: 95 km/h
- time = 0.75 h
- speed = distance ÷ time = 71.25 ÷ 0.75
- = 95 km/h
7.A car travels 23.75 km at an average speed of 95 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 23.75 ÷ 95
- = 0.25 h = 15 minutes
8.A train travels at 85 km/h for 45 minutes. How far does it travel?
Answer: 63.75 km
- time = 0.75 h
- distance = speed × time = 85 × 0.75
- = 63.75 km
9.Olivia travels 330 km in 3 hours. What is the average speed in km/h?
Answer: 110 km/h
- time = 3 h
- speed = distance ÷ time = 330 ÷ 3
- = 110 km/h
10.Mia travels 157.5 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 105 km/h
- time = 1.5 h
- speed = distance ÷ time = 157.5 ÷ 1.5
- = 105 km/h
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.
