An air traffic controller is monitoring two small planes flying at the same altitude. One is flying towards the control tower from the West at 120 miles per hour and is currently 5 miles away from the tower. The other plane is now on top of the tower and flying South at 150 miles per hour. In order to respect local safety rules the planes have to be always more than 4 miles from each other, or fly at different altitudes. Should the controller order one of the planes to change altitude, or will they always be farther than 4 miles from each other?
