The time in hours it takes a satellite to complete an orbit around the earth varies directly as the radius of the orbit (from the center of the earth) and inversely as the orbital velocity. if a satellite completes an orbit 720 miles above the earth in 13 hours at a velocity of 38,000 mph, how long would it take a satellite to complete an orbit if it is at 1900 miles above the earth at a velocity of 23,000 mph? (use 3960 miles as the radius of the earth.) round your answer to the nearest hundredth of an hour.
