Homework Statement



The average speed of an orbiting space shuttle
is 19800 mi/h. The shuttle is orbiting about
233 mi above the Earth’s surface. Assume the
Earth’s radius is 3963 mi.
How long does it take to circle the earth?
Answer in units of h.


Homework Equations



I think it may use V= x/t.


The Attempt at a Solution



t = 4199 mi / 19800 mi/h = .2120 h.

Orbiting the earth means it's traveling in a circle with radius 3963+233 mi. So the x in your equation is the circumference of that circle. What would that be?
