The latitude of any location on Earth is the angle formed by

The latitude of any location on Earth is the angle formed by the two rays drawn from the center of Earth to the location and to the equator. The ray through the location is the initial ray. Use 3960 miles as the radius of the Earth. Suppose City A is due north of City B. Find the distance between City A (north latitude 40 degree 17\' N) and City B (latitude 35 degree 47\' N) The distance between City A and City B is approximately miles. (Do not round until the final answer. Then round to the nearest mile as needed)

Solution

318 miles approx
