The speed of a moving sidewalk at an airport is 3 ft/sec. A person can walk 79 ft forward on the moving sidewalk in the same time it takes to walk 15 ft on a nonmoving sidewalk in the opposite direction. At what rate would a person walk on a nonmoving sidewalk?

looooooooool idk
(r + 3) / 79 = r / 15
15 r + 45 = 79 r
15 r + 45 = 79 r
