Math challenge

For any students who are following the blog, you may remember that I taught math.  So here's my international math problem for you:

How much are Koreans paying for gas in American measurements?

You'll need to convert Won to $, and Kilos to gallons. 

Take your answers to Ms. Hogue. There will be a raffle for a souvenir from Korea from all the right answers. (Must ahow you work.  You can find the conversion rate for Won to USD online)
