Find the distance in kilometers between two cities


Asked by maham237 @ in Mathematics viewed by 271 People


Find the distance in km between the following pair of cities, assuming they lie on the same north-south line. The radius of the Earth is approximately 6400 km.
City A, 35° N, and City B, 22° S

Answered by maham237 @



35+22 = 57 degrees between the two cities
The arc distance between them is radius x angle
Convert 57 degrees to radians is 57*Pi/180 = .995
Then 6400*.995 =6367 km.
