A world record was set in Eco-Marathon by a french team in 2003 called Microjoule with a performance of 10,705 miles per gallon. The microjoule runs on ethanol. If the cars are given 100 grams of ethanol (specific gravity = .789) and drive until the fuel runs out, how far did the microjoule drive in kilometers?

Pic unrelated, please help I'm a retard

100 grams of ethanol = 0.100kg = 0.100/0.789 = 0.127 liters
0.127 l = 0.127/3.785 = 0.0336 gallons
With this amount of fuel, the car runs 10,705*0.0336 = 360 miles
360 miles = 360*1.609344 = 579 km

Unless I made a mistake.
