The answer depends on the price of gasoline at the time of the trip and the fuel efficiency of the vehicle.
Assuming WDC stands for Washington, D.C. the distance to Cincinnati is just over 500 miles.
If the vehicle gets about 25 miles per gallon of gasoline, and at the price of gasoline at the time this answer was written (about $3.70/gal) you are looking at about $74 for a one way trip.
BE AWARE that the shortest route from Washington DC to Cincinnati goes through the Pennsylvania Turnpike which is a toll road.
