A satellite orbits at a distance from the Earth's center of about 4.40 Earth radii and takes 13.0 hours to go around once. What distance (in meters) does the satellite travel in one day?

drwls,
One day is 24/13 = 1.8462 revolutions.
Multiply that by 2 pi * R, where
R = 4.4 Earth radii.
The Earth's radius is about 6370 km. Look it up to make sure.
