Mario, who is training to use a radar system, detects an airplane flying at a constant speed and
heading in a straight line to pass directly over her location. She sees the airplane at an angle of
elevation of 159 and notes that it is maintaining a constant altitude of 6250 feet. One minute
later, she sees the airplane at an angle of elevation of 52. How far has the airplane traveled, to
the nearest foot? Determine and state the speed of the airplane, to the nearest mile per hour.
