If the average speed of an orbiting space shuttle is 18200 mi/h, determine the time required for it to circle?

If the average speed of an orbiting space shuttle is 18200 mi/h, determine the time required for it to circle the Earth. Make sure you consider the fact that the shuttle is orbiting about 200 mi above the Earth's surface, and assume that the Earth's radius is 3963 miles.

    18200 mi/h = 8136 m/s

    200 mi = 322000 m

    3963 mi = 6.38e6 m

    radius of orbit = 6.38e6 + 322000 = 6.70e6 m

    Circumference is πd = 2πr = 4.21e7 m

    4.21e7 / 8136 m/s = 5174 seconds = 1.44 hours
