You depart LAT 28°55.0'N, LONG 89°10.0'W, enroute to LAT 24°25.0'N, LONG 83°00.0'W. What is the true course and distance by mid-latitude sailing?

Correct Answer: Option D — 442 miles, 122°T

Mid-latitude sailing solves rhumb line navigation by treating the mean latitude as the parallel of origin. Applying latitude and longitude differences to standard Bowditch formulas calculates 442 miles distance along a 122°T true course.
