An air traffic controller spots two airplanes at the same altitude converging to a point as they fly at right angles to each other. One airplane is 75 kilometers from the point and has a speed of 150 kilometers per hour. The other is 100 kilometers from the point and has a speed of 200 kilometers per hour. (a) At what rate is the distance between the planes changing? km/h (b) How much time does the controller have to get one of the airplanes on a different flight path?
