two places are 264 km apart on the same line of longitude. calculate the difference between their lat

Question

Latitude and longitude

Answer 1

Assume earth's mean radius is 6370km. The length of arc on the line of longitude is 264km=rx where r=radius of earth and x is the difference in latitude measured in radians. So x=264/6370=0.04144 radians=2.37 degrees approx latitude.
