A pilot sets out from an airport and heads in the direction N 30°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.
(a) 423.8 mi (b) 408.8 mi (c) 309 mi (d) 216.41 mi (e) 312.41 mi
