The amount of sugar 
in the starting solution contributes to a 36% concentration, so we have
units of sugar in the solution.
Into this solution, Sharon wants to pour 
liters of water to obtain a smaller concentration of sugar in the overall solution:
So Sharon needs to add 
liters of water to the solution to get the desired concentration.
The solution to the problem is as follows:
To Washington DC, she travelled a total of 54538 - 54250 = 288 miles.
Therefore, 288 miles / 9 gal = 32 miles/gal.
