Two; the north and south poles. Because a compass will always point you in the direction of the poles due to their magnetic emission, if you start exactly at the north pole and travel due south one mile and due west one more mile, your compass will point you directly back to the pole, which you will be exactly one mile away from, and likewise for the south pole.

There would be 48 poles in a mile because 1 mile is equal to 1609.34 meters and 1609.34 divided by 30 is approximately 53.6, but since only whole poles are counted, there would be 48 poles.
This depends on the location; in more isolated areas there may be as few as one telephone pole in 5 miles, but in more populated areas there could be as many as 20 in a mile.
One.
Watts are a measure electrical power, and a mile is a measure of distance. You're trying to compare apples to oranges with this question. You could question how many watts a particular engine might take to propel a vehicle for for a mile, but that number would vary between engines.

a Nautical Mile is 6000 feet, regardless whether it is at either pole or the equator.
A watt is a unit of power, not a unit of length.
