A plane flying horizontally at an altitude of 1 mile and a speed of of 500mi/h passes directly over a radar station. Find the rate at which the distance from the plane to the station is increasing when it is 2mi away from the station.

Note: the distance is the actual distance, along the diagonal between the station and the plane.
