Joe filled up his car's gas tank. After travelling $165 \mathrm{~km}, \frac{3}{8}$ of the gas in the tank was used. At this rate, approximately how much farther can the car travel before its fuel tank is completely empty?
(A) $99 \mathrm{~km}$
(B) $440 \mathrm{~km}$
(C) $605 \mathrm{~km}$
(D) $264 \mathrm{~km}$
(E) $275 \mathrm{~km}$
Joe used $\frac{3}{8}$ of the gas in the tank after travelling $165 \mathrm{~km}$, and so he used $\frac{3}{8} \div 3=\frac{1}{8}$ of the gas in the tank after travelling $165 \div 3=55 \mathrm{~km}$.

Since Joe used $\frac{1}{8}$ of the gas in the tank to travel $55 \mathrm{~km}$, he used all the gas in the tank to travel $55 \times 8=440 \mathrm{~km}$.

If Joe has already travelled $165 \mathrm{~km}$, then he can travel another $440-165=275 \mathrm{~km}$ before the gas tank is completely empty.

ANSWER: (E)
