Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 105 km at an average speed of 35 km/h. How long does the trip take?
Answer: 3 hours
- time = distance ÷ speed = 105 ÷ 35
- = 3 h = 3 hours
2.A car travels 31.25 km at an average speed of 25 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 31.25 ÷ 25
- = 1.25 h = 1 hour 15 minutes
3.A car travels 30 km at an average speed of 120 km/h. How long does the trip take?
Answer: 15 minutes
- time = distance ÷ speed = 30 ÷ 120
- = 0.25 h = 15 minutes
4.Emma travels 25 km in 30 minutes. What is the average speed in km/h?
Answer: 50 km/h
- time = 0.5 h
- speed = distance ÷ time = 25 ÷ 0.5
- = 50 km/h
5.A car travels 90 km at an average speed of 60 km/h. How long does the trip take?
Answer: 1 hour 30 minutes
- time = distance ÷ speed = 90 ÷ 60
- = 1.5 h = 1 hour 30 minutes
6.A car travels 30 km at an average speed of 40 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 30 ÷ 40
- = 0.75 h = 45 minutes
7.Sienna travels 30 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 20 km/h
- time = 1.5 h
- speed = distance ÷ time = 30 ÷ 1.5
- = 20 km/h
8.Harper travels 67.5 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 45 km/h
- time = 1.5 h

- = 45 km/h
9.A train travels at 115 km/h for 15 minutes. How far does it travel?
Answer: 28.75 km
- time = 0.25 h
- distance = speed × time = 115 × 0.25

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.
