A drone is hovering at the top of the vertical tower 20 meter high. A car is moving in a straight line toward the base of the tower.  At a certain movement,  the car is 80 meters away from the base.  At the same moment , the drone begins to descend in a straight line to intercept the car. Assuming the drone and the car moving at the same speed,  at what distance from the base of the tower will the drone intercept the car?
