Problem-Solving and Data Analysis practice question
A car travels 150 kilometres on 10 litres of fuel. At the same rate, how many litres of fuel does it need to travel 375 kilometres?
Answer: 25
The car uses 1 litre per 15 kilometres, so 375/15 = 25 litres.
Common wrong answers
- If you answered 15
- 15 is kilometres per litre.
- If you answered 37.5
- 37.5 divides 375 by 10.
- If you answered 22.5
- 22.5 subtracts 150 from 375 and divides by 10.
