Question

An airplane has an airspeed of 530 kilometers per hour bearing N30°E. The wind velocity is 20 kilometers per hour in the direction N40°W. By finding the resultant vector representing the path of the plane relative to the ground, what is the ground speed of the plane?

549.7 km/h
530.4 km/h
523.5 km/h
537.2 km/h

Answer 1

Add the two vectors by separating the x and y components first and then taking the square root of the sum of the component squares.
