2. A low-flying jet aircraft covering a straight course is tracked by a radar station set 6 miles to one side of the flight path (see figure below). Here, x = (distance from a reference marker on the course), and s = (direct distance from aircraft to radar unit). A radar unit can measure only the "range" s and the rate of change as/at. Suppose the observed values are s = 10 miles and ds/at = 800 mph. Calculate the actual speed dx/dt of the aircraft. Top view - looking down F - X marker jet 6 S radar
