Guatemala City, Guatemala, and St Louis, Missouri, lie approximately on the same meridian. Guatemala City has a latitude of 15° N, and St Louis has a latitude of 39° N. Find the distance between these two cities. (The radius of the earth is 3960 mi. Round your answer to the nearest whole number)
This is a fraction of the whole earth circumference (pi * 2 * 3960)
39 - 15 = 24o of the entire 360
24/360 x (pi * 2 * 3960) = ....... miles apart
