Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Mia travels 315 km in 3 hours. What is the average speed in km/h?
Answer: 105 km/h
- time = 3 h
- speed = distance ÷ time = 315 ÷ 3
- = 105 km/h
2.A train travels at 70 km/h for 3 hours. How far does it travel?
Answer: 210 km
- time = 3 h
- distance = speed × time = 70 × 3
- = 210 km
3.A train travels at 30 km/h for 15 minutes. How far does it travel?
Answer: 7.5 km
- time = 0.25 h
- distance = speed × time = 30 × 0.25
- = 7.5 km
4.A train travels at 100 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 125 km
- time = 1.25 h
- distance = speed × time = 100 × 1.25
- = 125 km
5.Kai travels 18.75 km in 45 minutes. What is the average speed in km/h?
Answer: 25 km/h
- time = 0.75 h
- speed = distance ÷ time = 18.75 ÷ 0.75
- = 25 km/h
6.Max travels 27.5 km in 15 minutes. What is the average speed in km/h?
Answer: 110 km/h
- time = 0.25 h
- speed = distance ÷ time = 27.5 ÷ 0.25
- = 110 km/h
7.A train travels at 120 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 300 km
- time = 2.5 h
- distance = speed × time = 120 × 2.5
- = 300 km
8.A train travels at 40 km/h for 30 minutes. How far does it travel?
Answer: 20 km
- time = 0.5 h
- distance = speed × time = 40 × 0.5
- = 20 km
9.A car travels 82.5 km at an average speed of 110 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 82.5 ÷ 110
- = 0.75 h = 45 minutes
10.A train travels at 25 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 62.5 km
- time = 2.5 h
- distance = speed × time = 25 × 2.5
- = 62.5 km
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.
