6 An aircraft spotter on the ground observes a plane flying towards her at a constant altitude of 400 meters. She notes that when the angle of elevation from her to the plane is, this angle is increasing at a rate of 2 radians per minute. How fast was the distance between the spotter and the plane changing at that instant? Keep two decimal places in your final answer.
