Gas prices around the world
The price of gas varies around the world, due to the vagaries of exchange rates but mostly because of taxes and subsidies. Assuming your car gets 35 miles per gallon, here is how far $20 of gas will take you in various countries around the world:
Germany: 127 miles
Japan: 147 miles
United States: 342 miles
China: 385 miles
Saudi Arabia: 771 miles
Venezuela: 4,624 miles
