623. A vessel at LAT 14°10'N, LONG 61°00'W is to proceed to LAT 10°00'N, LONG 53°23'W. What is the course and distance by mid-latitude sailing?

Choice B is correct; mid-latitude sailing yields a course of 119.2T and a distance of 512 nautical miles. The mid-latitude was calculated as 12.0833N. Departure was determined to be 447 nautical miles east. The course was then calculated using the tangent function and converted to true degrees, resulting in 119.2T. Finally, the distance was calculated using the Pythagorean theorem, yielding 512 nautical miles.
