How fast the satellites go on each path?

Geo satellites have a proscribed speed since they must orbit in the equatorial plane of the planet to be stationary in the sky relative to points on the earth.
Polar orbits can be at any altitude, so the speed will vary depending.

Polar is just the direction, form north to south pole and back again.
Geostationary is 22 000 miles out around the equator rotating once per day in the same direction as the earth therefore effectively remaining over the same spot on the earth and thus the term "geostationary"
The distance out determines the speed. In the case of the cospas sarsat system they orbit once every 110 minutes or so, i.e. traveling very fast.

Hi. In both types of orbit the height is dependent on speed. A Polar orbit circles north to south or south to north. Geostationary orbits west to east at the same rate as the Earth.

huh? what kind of speed are you talking about? W/ respect to the ground or actual velocity to maintain orbit?
Geostationary don't move. they "hover" over one spot on the Earth. Their orbital period is 24 hours. While polar orbits will have a westward progression of the footprint. Thus requiring the clarification.
Furthermore, the eccentricity of each orbit will determine the satellites instantaneous velocity. Geostationary will have a near circular & need to maintain a high orbital velocity, but HEOs will varie greatly w/ time.

polar means a satellite Will orbit from the north to south poles. Geo is usually orbiting the equator.

Both the same .....allowing for the gap
