The car that I own can go `150` km with `25` litres of petrol. How far can it go with `30` litres of petrol?

Options

A. `"180 km"`
B. `"150 km"`
C. `"160 km"`
D. `"140 km"`

Explanation

To solve the problem step by step, we need to determine how far the car can travel with 30 litres of petrol based on its performance with 25 litres.

### Step 1: Determine the distance covered per litre of petrol
We know that the car can go 150 km with 25 litres of petrol. To find out how far it goes with 1 litre of petrol, we divide the total distance by the total litres of petrol.

\[ \text{Distance per litre} = \frac{\text{Total Distance}}{\text{Total Litres}} = \frac{150 \text{ km}}{25 \text{ litres}} = 6 \text{ km/litre} \]

### Step 2: Calculate the distance for 30 litres of petrol
Now that we know the car travels 6 km for every litre of petrol, we can find out how far it will go with 30 litres by multiplying the distance per litre by the number of litres.

\[ \text{Distance for 30 litres} = \text{Distance per litre} \times \text{Number of litres} = 6 \text{ km/litre} \times 30 \text{ litres} = 180 \text{ km} \]

### Final Answer
The car can go **180 km** with 30 litres of petrol.
