Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.Chloe travels 68.75 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 55 km/h
- time = 1.25 h
- speed = distance ÷ time = 68.75 ÷ 1.25
- = 55 km/h
2.A train travels at 110 km/h for 15 minutes. How far does it travel?
Answer: 27.5 km
- time = 0.25 h
- distance = speed × time = 110 × 0.25
- = 27.5 km
3.Noah travels 12.5 km in 30 minutes. What is the average speed in km/h?
Answer: 25 km/h
- time = 0.5 h
- speed = distance ÷ time = 12.5 ÷ 0.5
- = 25 km/h
4.Grace travels 180 km in 3 hours. What is the average speed in km/h?
Answer: 60 km/h
- time = 3 h
- speed = distance ÷ time = 180 ÷ 3
- = 60 km/h
5.A car travels 45 km at an average speed of 30 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 45 ÷ 30
- = 1.5 h = 1 hour 30 minutes
6.A car travels 225 km at an average speed of 75 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 225 ÷ 75
- = 3 h = 3 hours
7.A train travels at 20 km/h for 45 minutes. How far does it travel?
Answer: 15 km
- time = 0.75 h
- distance = speed × time = 20 × 0.75
- = 15 km
8.A car travels 60 km at an average speed of 40 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 60 ÷ 40
- = 1.5 h = 1 hour 30 minutes
9.A car travels 26.25 km at an average speed of 105 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 26.25 ÷ 105
- = 0.25 h = 15 minutes
10.A train travels at 120 km/h for 30 minutes. How far does it travel?
Answer: 60 km
- time = 0.5 h
- distance = speed × time = 120 × 0.5
- = 60 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.
