Problem: Assuming tha tthe earth is a sphere of radius 4000 miles, what is the difference in latitudes of two cities, one of which is 325 miles due north of the other.
I drew a picture and made the radius of the circle equal to 4000 miles and had 2 points. I made one point at 0 miles and the other at 325 miles. After multiplying 4000 by (325/Pi) I received 3.918 degrees. I know the answer is 4.655 degrees, but I don't know how to correctly solve the problem. Please help! Thanks!
