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 780 miles above the earth in 11 hours at a velocity of 28,000 mph, how long would it take a satellite to complete an orbit if it is at 1,200 miles above the earth at a velocity of 26,000 mph? (Use 3960 miles as the radius of the earth.)
