The speed of a moving sidewalk at an airport is 2ft/sec. A person can walk 93ft forward on the moving sidewalk in the same time it takes to walk 12ft on a non moving sidewalk in the oppsite direction. At what rate would a person walk on a nonmoving sidewalk?
T = d/r = 93Ft/2Ft/s = 46.5 s. To ride 93 Ft.
V = d/T = 12Ft/46.5s. = 0.258 Ft./s.
