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?
I think the problem is the same as if it was a 30 degree angle slope to 200 m. It is 400m. The difference is therefore 200m.
