Explanation:

- First, calculate the distance the car covers per litre of petrol:

$$ \text{Distance per litre} = \frac{75.5 \, \text{km}}{3.5 \, \text{litres}} = 21.57 \, \text{km/litre} $$

- Next, find out how much distance can be covered in 28 litres:

$$ \text{Distance with 28 litres} = 21.57 \, \text{km/litre} \times 28 \, \text{litres} = 604 \, \text{km} $$

- Option 1: 603 km - This is a bit less than the correct calculation.

- Option 2: 602 km - Also less than the answer.

- Option 3: 604 km - This matches the calculated distance.

- Option 4: 600 km - Slightly less and thus incorrect.
