This is a supplementary answer in addition to the excellent answer from @asdfex, with an attempt to explain things in simplified terms, as, judging from the comments, OP is still confused with Geostationary Orbit.
An object placed in Geostationary orbit (the orbit lies in Earth equatorial plane) would appear motionless to ground observer.
If I am in geo-stationary orbit, I am moving 0 units/hour relative to the ground.
This is true only when the "units" are angular units, i.e. degrees or radians. This means that observer on the ground and the object in GSO are rotating around the center of the Earth with the same angular speed.
When the "units" are distance units, i.e. meters or miles etc., the above statement is not true, because linear velocities of observer on the ground and the object in GSO are different due to the fact that their corresponding radii are different.
I guess this is where confusion might be coming from.
Now, to address ground/LEO/GSO relative speed:
If I am walking, the ground is stationary, and I move X units/hour relative to the ground.
If I am in low-earth orbit, then I am still moving X units/hour relative to the ground, only its a much bigger X.
The key misconception here (comparison of apples to oranges) lies in the fact that when a person is walking on the ground, he/she is not orbiting, whereas in LEO he/she is orbiting. This is why the relative-to-the-ground linear velocity seems that much bigger.
For the discussion below, let's assume everything happening in equatorial plane, orbits are circular and prograde, no perturbations, drag, solar wind etc. and all numbers are approximate/rounded.
Ground speed. The Earth makes one full revolution around its axis in 1,436 minutes, hence the Earth's rotational speed is 0.25 degrees/min. This makes linear velocity of an observer on equator (at 6371 km radius) equal to 460 m/s (1,029 mph)
a) Orbiting at the ground level. Assuming perfectly spherical Earth without hills/mountains and absence of atmosphere (so that there's no drag), in order to orbit the Earth at 1 meter above its surface, one needs to move with much higher rotational speed compared to earth: 4.27 degrees/min (17 times faster than earth). This corresponds to linear speed of 7,910 m/s (17,694 mph).
The relative orbital speed of the "ground-level" orbiting person to another observer on the ground is 4.27 - 0.25 = 4.02 deg/min.
Relative linear speed is 7,910 - 460 = 7,450 m/s.
- b) Orbiting in LEO. Let's assume 400km altitude. Orbital angular speed is 3.66 degrees/min, linear speed is 7,672 m/s (17,162 mph).
Relative angular speed is 3.66 - 0.25 = 3.41 deg/min,
Relative linear speed is 7,672 - 460 = 7,212 m/s.
- c) Orbiting in GSO. The altitude for this orbit is defined as 35,786km. Orbital angular speed is 0.25 deg/min, linear speed is 3,075 m/s (6,879 mph)
Relative angular speed is 0.25 - 0.25 = 0 deg/min,
Relative linear speed is 3,075 - 460 = 2,615 m/s.
If the orbital radius gets further than GSO radius, the object in that orbit would appear (to observer on the ground) to move "backwards" whilst an object in LEO would appear to move "forward" (because in angular terms Earth would rotate quicker than object in the higher-than-GSO orbit) although objects in both orbits (LEO and higher than GSO) and the Earth are rotating in the same direction.
Therefore, from observer on the ground point of view, comparison of relative to the ground linear speeds (between LEO, GSO and orbit beyond GSO) are not as relevant as comparison of angular speeds.
P.S. Motion of a person in GSO relative to a person on the ground can be described by the following very simplified analogy:
Imagine a "person A" sitting in a seat of a merry-go-round;
Consider another "person B" standing right in the center of the merry-go-round (therefore spinning with it) with his/her arm raised horizontally and pointing a finger to the person in the seat.
The person A is analogy to a person in GSO orbit, and the finger of the person B becomes analogy to an observer on the Earths equator.
Whilst the merry-go-round is spinning, the person's B finger and the person A (in the seat) appear motionless between each other, but in terms of distance, for a given time of few seconds the finger moves few inches, whilst the person A moves few feet.
