Question 334792
OK
The space shuttle's orbit, then, is 8000 plus 480 or 8480 miles in diameter.  The distance around the orbit is the circumference of the orbit and this can be found by the formula: C=(pi)D where C is the circumference, D is the diameter and (pi) equals 3.14159265---. So C=(pi)*8480=3.14159265*8480= 26640.706 miles. and we are told that the space shuttle traverses that distance ever 5 hours. So in 1 hour the space shuttle travels (26640.706)/5= 5328.1412 miles.  I suppose we could round off (pi) to 3.14 and still be within 10 miles.

Hope this helps--ptaylor
