4. At 1919 your position is LAT 37°00.5'N, LONG 75°43.8'W. At 2019 your position is LAT 37°00.0'N, LONG 75°30.0'W. What is the course made good?
The course made good is determined by the change in latitude and longitude between the two positions. Calculating the departure and latitude change, then using trigonometry, yields a course of 093T, slightly south of due east.
