After flying 300 miles in this direction, the plane suddenly develops engine trouble. The navigator calculates there is enough fuel left to fly only 375 miles. Can the plane return to the Atlanta airport or must the pilot seek a closer one to make an emergency landing? If it can return, in what direction must it head for the shortest return?
