A plane flying horizontally at an altitude of h mi and a speed of v mi/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 L mi away from the station. The distance is changing at the rate of: mi/h (in terms of L, h and v) A plane flying horizontally at an altitude of h mi and a speed of v mi/h passes directly over a radar station.
