Let's solve each problem step by step using the formula:
>
Speed = Distance ÷ Time
We'll make sure to include the correct units in our answers.

1. A lorry drove one hundred miles in two hours. How fast was it travelling?
- Distance = 100 miles
- Time = 2 hours
Speed = 100 miles ÷ 2 hours = 50 miles per hour (mph)
✔ Answer: 50 mph

2. A bus drove one hundred and eighty kilometres in three hours. How fast was it travelling?
- Distance = 180 km
- Time = 3 hours
Speed = 180 km ÷ 3 hours = 60 km/h
✔ Answer: 60 km/h

3. A boat sailed twenty miles in four hours. How fast was it travelling?
- Distance = 20 miles
- Time = 4 hours
Speed = 20 miles ÷ 4 hours = 5 miles per hour (mph)
✔ Answer: 5 mph

4. A car drove 360 kilometres in 9 hours. How fast was it travelling?
- Distance = 360 km
- Time = 9 hours
Speed = 360 km ÷ 9 hours = 40 km/h
✔ Answer: 40 km/h

5. A plane flew one thousand and eighty miles in nine hours. How fast was it travelling?
- Distance = 1,080 miles
- Time = 9 hours
Speed = 1,080 miles ÷ 9 hours = 120 miles per hour (mph)
✔ Answer: 120 mph
---
✔ Final Answers:
1.
