If Cairo is 30º North and the Equator is 0º, then that is 30 degrees.Latitude is a constant and does not vary when you go north or south, and Each degree is 60 miles, so it's 30 X 60 which would be 1800 Miles

The longitude doesn't matter; only the latitude and the radius of the earth. If Cairo is at 30 degrees north, it's easy. Thirty degrees is one-twelfth of a circle.
Using 3960 miles as the earth's radius, the circumference is 2 pi x 3960 = 24,880 miles; and one-twelfth of that is 2,073 miles.
That's your answer.
