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 B — 442 miles, 122°T

Mid-latitude sailing approximates the Earth as a plane for short distances. Using the mean latitude to convert departure to difference in longitude, the calculation yields a course of 122°T and a distance of 442 miles. This method is accurate for the distances and latitudes specified in the problem.
