The origin of the x-y coordinate system is fixed relative to the earth. The velocity of the Nimitz relative to the earth is      vA = 15j knots The velocity of the F-15 relative to the Nimitz is      vB/A = 300 cos45i + 300 sin45j knots Using the relative velocity equation, the velocity of the F-15 relative to the earth can be obtained as,      vB = vA + vB/A           = 300 cos45i + (15 + 300 sin45)j           = 212.1i + 227.1j The magnitude of the velocity of the F-15 relative to the earth is Trigonometry can be used to find the direction of the F-15 relative to the earth, giving      θ = tan-1 (212.1/227.1) = 43.0o East of North
