An airplane pilot checks her instruments and finds that the air speed of the plane is 325 km/h. the instruments show that the plane is pointed in a direction (s 30 w). a radio report indicates that the wind velocity is 80 km/h (w). what is the velocity of the plane relative to the ground as it would be recorded by an air traffic controller in a nearby airport?
