A communications satellite is in a synchronous orbit that is 3.6 x 107 m directly above the equator. The satellite is located between two cities almost on the equator that are separated by a distance of 2.9 x 106 m. Find the time it takes for a telephone call to go by way of satellite between these cities. Ignore the curvature of the earth.
