Question

Difference in Latitudes Assuming that Earth is a sphere of radius 6378 kilometers, what is the difference in the lat- itudes of Syracuse, New York and Annapolis, Maryland, where Syracuse is 450 kilometers due north of Annapolis?

Answer 1

Circumference of Earth is 2 pi R and that equals 360o
(450/circumference)(360) should give you difference in degrees of latitude.
