In Exercise, solve the given problems.

A water pumping station is to be built on a river at point P in order to deliver water to points A and B. See Fig. 2.48. The design requires that ∠APD = ∠BPC so that the total length of piping that will be needed is a minimum. Find this minimum length of pipe.
