Assume that the cities lie on the same north-south line and that the radius of the earth is 6400 km. Find the distance between City E, 28 degree N and City F, 13 degree S. (Round to the nearest kilometer.)

Solution

Solution:

Radius of earth = 6400 Km

City E, 28°N and City F, 13°S

= 28° + 13° = 41° X /180° = 0.7156 radians

Distance S = r = (6400km * 0.7156 radians) = 4580 km
