An Escalator At The St. Louis Galleria
x rate = 5/(2(3^.5)) feet per second
y rate = (5/6) feet per second
[ d = (x^2 + y^2)^.5 ] The rate for x squared added to the rate for y squared is also equal to the rate for d squared. Confirm this rate (speed) related relationship:
(r for d)^2 = (r for x)^2 + (r for y)^2
= (______________)^2 (feet per second)^2.
