The answer depends on your latitude, as follows:
V = Cos (lat) * 1037.56
where V is your speed in miles per hour. For V in km/hr the equation is:
V = cos(lat) * 1669.79
These answers are only valid for latitudes between the arctic and antarctic circles; at the poles, you will have permanent darkness on at least some days of the year.

The first answer is wrong because by staying above the same spot on the earth at the equator a satellite would be in darkness for part of the orbit around the earth.
On the other hand, if the orbit is around the earth from pole to pole and from the evening at the equator to morning at the equator, the satellite would always be visible to the sun and never be in darkness.
There may be a Russian satellite that does this as most pole to pole satellites were put there by the Russians.

At the equator, you have to go 25,000 miles (once around the earth) in 24 hours. That would be a little over 1,000 miles an hour.
That's faster than most passenger planes, but not out of the question for the concorde supersonic, or any number of military planes.
As you go further north or south, the speed decreases. At the poles, the sun shines for 24 hours a day for six months in a row. You wouldn't need to move around at all!

The sun gets back to the same position over the earth in 24 hours. You have to do the same to keep pace. Find out the circumference of the earth at your latitude in the units of your choice, then divide by 24 to get the per hour part.
A catch - if you are poleward of the Arctic or Antarctic circles, the sun goes below the bulge of the earth for up to six months at a time. Pacing it does no good until your hemisphere points back towards it.

The circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour.
In order to never get out of the reach of the sun...you would have to match the speed at which the earth rotates...about 1042 mph at the equator.

Even ignoring the seasons, the nearer you are to the pole, the less distance you have to travel to get round the world, so you don't need to travel so fast to keep up with the sun.
At the latitiude of northern europe and Canada, a standard airliner can keep up with the sun.
No airliner can keep up with the sun at the equator - Concorde is dead, folks.

Just over 1000mph at the equator..
The closer you get to a pole in the
summer the slower you can go ..
For example, Midnight sun in the Summer at the north pole..

This would also depend on your altitude. After you get so high, you wouldn't have to move at all.

Depends on your lattitude and the season.
