Sorry.
Point A is 23°33'S and point B is 47°56'S. If an aircraft is traveling from from A to B, what is the Ch Lat and what is the D Lat?
Ch Lat comes out to be 24°23'S. I got that.
I can't seem to figure out how to calculate D Lat. The answer is 1463'S. but I dont know how they came up with that number.
