Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 52.5 km at an average speed of 105 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 52.5 ÷ 105
- = 0.5 h = 30 minutes
2.A car travels 27.5 km at an average speed of 55 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 27.5 ÷ 55
- = 0.5 h = 30 minutes
3.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
4.Amelia travels 175 km in 2 hours 30 minutes. What is the average speed in km/h?
Answer: 70 km/h
- time = 2.5 h
- speed = distance ÷ time = 175 ÷ 2.5
- = 70 km/h
5.A car travels 100 km at an average speed of 40 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 100 ÷ 40
- = 2.5 h = 2 hours 30 minutes
6.A train travels at 30 km/h for 3 hours. How far does it travel?
Answer: 90 km
- time = 3 h
- distance = speed × time = 30 × 3
- = 90 km
7.Sienna travels 22.5 km in 15 minutes. What is the average speed in km/h?
Answer: 90 km/h
- time = 0.25 h
- speed = distance ÷ time = 22.5 ÷ 0.25
- = 90 km/h
8.A train travels at 120 km/h for 1 hour 30 minutes. How far does it travel?
Answer: 180 km
- time = 1.5 h
- distance = speed × time = 120 × 1.5
- = 180 km
9.A car travels 78.75 km at an average speed of 105 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 78.75 ÷ 105
- = 0.75 h = 45 minutes
10.A train travels at 115 km/h for 1 hour 15 minutes. How far does it travel?
Answer: 143.75 km
- time = 1.25 h
- distance = speed × time = 115 × 1.25
- = 143.75 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.
