Two ways up (Posted on 2002-05-05) Difficulty: 3 of 5
A tower, 200 feet high, has an elevator inside it, and a spiral stairway winding its way around the tower at a constant 30 degree angle with the horisontal.

Given the tower's radius of 10 feet, what is the difference between the distance covered by a person going up in the elevator, versus one climbing the stairs?

The person going up the stairs would not walk exactly 10 feet from the center {right against the wall}. Chances are they would walk a fes feet away from the wall which would increase the radius. Without this information the best possible answer would be an approximation.
