(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Gasoline yields 4.8x10^7 J/kg when burned. How much energy does a car use travelling a distance of 150 km if it gets 25 miles per (British) gallon? Assume that the density of gasoline is 68% that of water.

2. Relevant equations

3. The attempt at a solution

I dont really know where to begin with this question. All i know is that 25mpg is equal to 40.225km per gallon.

Any suggestions?
