Question

Transcribed Image Text:An airliner passes over an airport at noon traveling 510 mi/ hr due east. At 1:00 p.m., another airliner passes over the same airport at the same
elevation traveling due north at 570 mi / hr. Assuming both airliners maintain their (equal) elevations, how fast is the distance between them
changing at 3:00 p.m.?
The equation relating the horizontal distance between the first airliner and the airport, a, the horizontal distance between the second airliner and
the airport, b, and the horizontal distance between the two airliners, c is
Differentiate both sides of the equation with respect to t.
