The amount of sugar 
in the starting solution contributes to a 36% concentration, so we have
units of sugar in the solution.

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.
(4/5) / (4/9) = 4/5 * 9/4 = 36/20 = 9/5 = 1 4/5 miles per hour
so B.) one and four-fifths mph
