Assign variables to everything.

E = fuel efficiency, 4.4 mpg
d = distance expected, 55 miles
p = diesel fuel price, 3.67 dollars per gallon
y = cost expected for the trip just in fuel, unknown. Dollars.

Start with d, and use the ratios E and p. You are looking for a formula for y. Just watch the units carefully in forming your formula.
y=d*(?)*(?)
