The least fuel efficient car is a Bugati, which get only 10 miles per gallon. How many feet per fluid ounce is this? Note: one gallon = 4 quarts, one mile=5280 feet, 1 quart = 32 fluid ounces.
With one gallon it travels 10 * 5280 ft = 52800 ft
One ounce is 1/128th of a gallon, so it travels 1/128th of 52800ft = 412.5 ft
