A pilot sets out from an airport and heads in the direction N30°W, flying at a constant speed of 305 mi/h. Forty-five minutes later the pilot makes a course and speed correction and now heads in the direction N 50°W and reduces her speed to 175 mi/h. Half an hour later, engine trouble forces her to make an emergency landing. Find the distance between the airport and the final landing point.
