A factory `D` is to be connected by a road with a straight railway line on which a town `A` is situated. The distance `D B` of the factory to the railway line is `5sqrt(3)k mdot` Length `A B` of the railway line is 20km. Freight charges on the road are twice the charges on the railway. The point `P(A P
