The speed of a moving sidewalk at an airport is 7 ft/sec. A person can walk 74 ft forward on the moving sidewalk in the same time it takes to walk 15 ft on a non moving sidewalk in the opposite direction. At what rate would a person walk on a non moving sidewalk

10.56 ft/s.

Speed of side walk = 7 ft/s

time taken to travel 74 ft on the moving sidewalk = time taken to walk 15 ft on non moving side walk.

We know,

Rate at which person walk on non moving side walk is equal to 10.56 ft/s.
