Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 85 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 212.5 km
- time = 2.5 h
- distance = speed × time = 85 × 2.5
- = 212.5 km
2.Kai travels 18.75 km in 15 minutes. What is the average speed in km/h?
Answer: 75 km/h
- time = 0.25 h
- speed = distance ÷ time = 18.75 ÷ 0.25
- = 75 km/h
3.A train travels at 30 km/h for 2 hours 30 minutes. How far does it travel?
Answer: 75 km
- time = 2.5 h
- distance = speed × time = 30 × 2.5
- = 75 km
4.A car travels 250 km at an average speed of 100 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 250 ÷ 100
- = 2.5 h = 2 hours 30 minutes
5.A car travels 81.25 km at an average speed of 65 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 81.25 ÷ 65
- = 1.25 h = 1 hour 15 minutes
6.A car travels 18.75 km at an average speed of 25 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 18.75 ÷ 25
- = 0.75 h = 45 minutes
7.A car travels 75 km at an average speed of 100 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 75 ÷ 100
- = 0.75 h = 45 minutes
8.A car travels 118.75 km at an average speed of 95 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 118.75 ÷ 95
- = 1.25 h = 1 hour 15 minutes
9.A car travels 137.5 km at an average speed of 110 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 137.5 ÷ 110
- = 1.25 h = 1 hour 15 minutes
10.Mia travels 22.5 km in 45 minutes. What is the average speed in km/h?
Answer: 30 km/h

- = 30 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.
