Solve the problem.A plane flying with a tailwind flew at a speed of 470 mph, relative to the ground. When flying against the tailwind, it flew at a speed of 330 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 = 470 y = 330 B. x + y = 330 x - y = 470 C. x + y = 470 x - y = 330 D. x + y = 330 y = 470
