Answer
Andrew's car consumes 7.4 kilometers per liter.
Solution
1. Andrew drives \(518\) km using \(70\) litres of petrol.
2. The fuel consumption rate is calculated by dividing the distance by the amount of petrol:
\[
\text{Fuel Consumption Rate} = \frac{518 \text{ km}}{70 \text{ L}}
\]
3. Dividing gives:
\[
\frac{518}{70} = 7.4 \text{ km/L}
\]
Thus, the fuel consumption rate of Andrew's car is \(7.4\) km per litre.

To find Andrew's fuel consumption rate in kilometers per liter, you simply divide the distance he can travel on a full tank by the capacity of the tank. So, that would be \( 518 \text{ km} \div 70 \text{ liters} = 7.4 \text{ km/l} \). This means Andrew's car can travel 7.4 kilometers for every liter of petrol! Now, it’s interesting to think about how this figure can impact driving habits! Knowing your fuel efficiency not only helps with budgeting for petrol costs but can also encourage habits like smoother driving, maintaining speed limits, and regular vehicle maintenance. All these contribute to better fuel consumption, keeping both your wallet and the environment happy!
