Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A train travels at 60 km/h for 1 hour 40 minutes. How far does it travel?
Answer: 100 km
- time = 1.6667 h
- distance = speed × time = 60 × 1.6667
- = 100 km
2.A car travels 112.5 km at an average speed of 90 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 112.5 ÷ 90
- = 1.25 h = 1 hour 15 minutes
3.A train travels at 30 km/h for 1 hour 40 minutes. How far does it travel?
Answer: 50 km
- time = 1.6667 h
- distance = speed × time = 30 × 1.6667
- = 50 km
4.Mason travels 100 km in 1 hour 40 minutes. What is the average speed in km/h?
Answer: 60 km/h
- time = 1.6667 h
- speed = distance ÷ time = 100 ÷ 1.6667
- = 60 km/h
5.A car travels 60 km at an average speed of 90 km/h. How long does the trip take?
Answer: 40 minutes
- time = distance ÷ speed = 60 ÷ 90
- = 0.6667 h = 40 minutes
6.A car travels 150 km at an average speed of 90 km/h. How long does the trip take?
Answer: 1 hour 40 minutes
- time = distance ÷ speed = 150 ÷ 90
- = 1.6667 h = 1 hour 40 minutes
7.A car travels 75 km at an average speed of 90 km/h. How long does the trip take?
Answer: 50 minutes
- time = distance ÷ speed = 75 ÷ 90
- = 0.8333 h = 50 minutes
8.A car travels 67.5 km at an average speed of 30 km/h. How long does the trip take?
Answer: 2 hours 15 minutes
- time = distance ÷ speed = 67.5 ÷ 30
- = 2.25 h = 2 hours 15 minutes
9.A car travels 37.5 km at an average speed of 30 km/h. How long does the trip take?
Answer: 1 hour 15 minutes
- time = distance ÷ speed = 37.5 ÷ 30
- = 1.25 h = 1 hour 15 minutes
10.A train travels at 120 km/h for 50 minutes. How far does it travel?
Answer: 100 km
- time = 0.8333 h
- distance = speed × time = 120 × 0.8333
- = 100 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.
