Using the GRS1980 ellipsoid, it is exactly

111,693.865 meters.

While the distance between meridians changes with latitude, parallels are about 111 km from each other from the equator to the pole (you can look up the exact..) What is different about the pole is it is a point not a line..picture a circle of 89 degrees with a point in the middle..the radius is 111 km. Of course the earth is not a perfect sphere (but it's pretty darn close) it bulges at the equator and is flattened at the poles and topography may make minor differences in the distance if you were walking. Look at a polar projection of either pole. Many maps we use, like the Mercator, have great distortion in the polar regions (the parallels seem farther apart at the poles) this is just the difficulty you have taking a sphere and making it into a flat map.

On average, one degree of latitude is about 60 nautical miles (one nautical mile per minute of latitude). As the poles are slightly flattened, I would expect the distance from 89 degrees north to 90 degrees north to be a little less than this, but not much less.

Do you want the Magnetic North Pole, Physical North Pole, or the city in the Yukon that is named 'North Pole'?

1 degree or about 300 miles.

It is 111.6937 km.

From the equator to 1 degree North, it is 111.5744 km.

you have answered the question already...because the earth is a geoid and the poles are flat 90 degrees is just a projected place and not physical.
