Use speed = distance ÷ time, distance = speed × time and time = distance ÷ speed. Change minutes to hours (÷ 60) before calculating.
1.A car travels 63.75 km at an average speed of 85 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 63.75 ÷ 85
- = 0.75 h = 45 minutes
2.Layla travels 172.5 km in 1 hour 30 minutes. What is the average speed in km/h?
Answer: 115 km/h
- time = 1.5 h
- speed = distance ÷ time = 172.5 ÷ 1.5
- = 115 km/h
3.Kai travels 37.5 km in 1 hour 15 minutes. What is the average speed in km/h?
Answer: 30 km/h
- time = 1.25 h
- speed = distance ÷ time = 37.5 ÷ 1.25
- = 30 km/h
4.A car travels 25 km at an average speed of 50 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 25 ÷ 50
- = 0.5 h = 30 minutes
5.A car travels 187.5 km at an average speed of 75 km/h. How long does the trip take?
Answer: 2 hours 30 minutes
- time = distance ÷ speed = 187.5 ÷ 75
- = 2.5 h = 2 hours 30 minutes
6.A car travels 42.5 km at an average speed of 85 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 42.5 ÷ 85
- = 0.5 h = 30 minutes
7.A car travels 45 km at an average speed of 60 km/h. How long does the trip take?
Answer: 45 minutes
- time = distance ÷ speed = 45 ÷ 60
- = 0.75 h = 45 minutes
8.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
9.A car travels 22.5 km at an average speed of 45 km/h. How long does the trip take?
Answer: 30 minutes
- time = distance ÷ speed = 22.5 ÷ 45
- = 0.5 h = 30 minutes
10.A train travels at 35 km/h for 45 minutes. How far does it travel?
Answer: 26.25 km
- time = 0.75 h
- distance = speed × time = 35 × 0.75
- = 26.25 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.
