depends on what part of the earth you are flying over.
at the equator, about 1000 mph, less as you get away from the equator, assuming you are staying at the same latitude

It actually depends on your latitude. The closer you are to the pole, the slower you have to fly (assuming you flew from east to west).
Essentially what you have to do is fly westward at the same speed at which the earth is rotating. Near the equator, the linear velocity of the earth is much faster than the linear velocity at...say...34 degrees latitude which is faster still than 89 degrees latitude.
The angular velocity of the earth is 360 degrees about every 24 hours, so all parts of the earth rotate at the same angular velocity, but because the distance from the axis to the surface is greatest at the equator and smallest near the poles, the linear velocity or tangential velocity of a point on the planet's surface is different.
If you flew your plane along the equator from east to west, you would have to fly (approximately) 25,125 miles every 24 hours, which is just about 1050 miles per hour. If you flew your plane at 34 degrees latitude from west to east, then you only have to fly about 20,600 miles every 24 hours which is about 860 miles per hour. And if you flew near the north pole (89 degrees latitude) in an east to west direction, then you only have to go about 69 miles in 24 hours and that is about 3 miles per hour (which is too slow for an airplane and you could almost walk that fast).
To calculate the approximate speed, you will need, simply take the cosine of the latitude and multiply it times the radius of the earth and then times 2 times pi to get the circumfrence of the earth at that latitude. (it is an approximation only because the earth is not an exact sphere). That will tell you how far you have to fly in 24 hours.

That depends on your latitude (how far north or south).
At the poles, you could stand still for 6 months and never see the sun set.
At the equator, you would need to match the rate of rotation of the earth: 24,900 miles around in 24 hours, or about 1037 MPH.

HOW ABOUT 0 MPH? !!!!!!
WHAT IF YOU WENT STRIGHT UP IN A HELICOPTER, AND JUST "HOVERED" THERE INDEFINATELY. THE SUN WOULD NEVER SET AND COULDN'T YOU LET THE OTHER SIDE OF THE WORLD COME TO YOU??

if you stood at the north or south pole it would be 1 rpd! [ 1 revolution per day]

i guess as fast as the earth is rotating given your latitude
