73. A vessel steams 720 miles on course 058°T from LAT 30°06.0'S, LONG 31°42.0'E. What are the latitude and longitude of the point of arrival by mid-latitude sailing?

Mid-latitude sailing from 3006.0'S, 3142.0'E on a course of 058T for 720 NM results in an arrival position of LAT 2344'S, LONG 4307'E. This is calculated by determining the northing and easting components using plane sailing formulas, accounting for the mid-latitude, and applying these changes to the initial coordinates.
