A jet aircraft maintains a constant airspeed of 500 miles per hour in the direction due south. The velocity of jet stream is 80 miles per hour in a northeasterly direction. Find the actual speed and direction of the aircraft relative to the ground. (A northeasterly (NE) direction would be 45 degrees north of due East (E).)​​
