Hello!
Let the x-axis be from W to E and the y-axis from S to N. Then the own velocity of an airplane is represented by the vector
(in mph).
The wind velocity is represented by the vector
("blows from the W" means "to the E").
The combined velocity is
The magnitude of V (the speed) is (mph).
The direction is which means "N to the E".
The answer: the speed is about 263.25 mph, the direction is about N 13.43 degrees E.
