Question

The number of litres of diesel used by car X is ______.

Options

• $$\frac{72}{x-3}$$ litres

• $$\frac{72}{x+3}$$ litres

• $$\frac{72}{x}$$ litres

• $$\frac{12}{x}$$ litres

Answer 1

The number of litres of diesel used by car X is `underlinebb(72/x litres)`.

Explanation:

Car X travels x km on 1 litre, so it uses 72 ÷ x litres to travel 72 km. The expressions using x – 3 or x + 3 do not describe car X’s mileage and `12/x` is not the required quantity.
