Determine the difference of latitudes, DLAT, given the ship's initial position P1: (78° 54' S, 095° 22' E) and final position P2: (33° 12' S , 13° 15' W).

Answer 1

To determine the difference in latitudes, we need to subtract the latitude of the initial position from the latitude of the final position.

Initial latitude in degrees: 78° 54' S
Final latitude in degrees: 33° 12' S

To convert the minutes and seconds to decimal degrees:
78° 54' = 78 + (54/60) = 78.9
33° 12' = 33 + (12/60) = 33.2

Difference in latitudes: 78.9 - 33.2 = 45.7 degrees

Therefore, the difference in latitudes (DLAT) is 45.7 degrees.
