A car can travel 360 km in 12 litres of petrol. How much distance will it travel in 20 litres of petrol?

Answer

To solve the problem step by step, we will use the concept of ratios and proportions.

### Step 1: Understand the given information
We know that a car can travel 360 km using 12 litres of petrol.

### Step 2: Find the distance travelled per litre of petrol
To find out how much distance the car travels with 1 litre of petrol, we divide the total distance by the total litres of petrol.

\[ \text{Distance per litre} = \frac{360 \text{ km}}{12 \text{ litres}} = 30 \text{ km/litre} \]

### Step 3: Calculate the distance for 20 litres of petrol
Now that we know the car travels 30 km for every litre of petrol, we can calculate the distance for 20 litres by multiplying the distance per litre by the number of litres.

\[ \text{Distance for 20 litres} = 30 \text{ km/litre} \times 20 \text{ litres} = 600 \text{ km} \]

### Conclusion
The car will travel **600 km** using 20 litres of petrol.
