Solve.A plane flying with a tailwind flew at a speed of 420 mph, relative to the ground. When flying against the tailwind, it flew at a speed of 300 mph. Express these relationships as equations. Let x represent the speed of the plane in calm air and let y represent the speed of the wind.
A. x + y = 420 y = 300 B. x + y = 300 x - y = 420 C. x + y = 300 y = 420 D. x + y = 420 x - y = 300
