An airplane has a velocity of 400 km/h relative to the wind. At the same time, a wind blows northward with a speed of 75 km/h relative to earth. Find the direction that the airplane must head in order to move in an easterly direction relative to earth.

Answer 1

Wouldn't it need to fly in a direction that would cancel the North drift?

400sinTheta=75 where theta is the angle S of E.

Answer 2

is there any answer
