(1) A moving sidewalk at an airport moves at a rate of 1.8ft/sec .Walking on the moving sidewalk , camille travels 105 ft forward inthe time it takes to travel 51 ft in the opposite direction . Howfast would camile be walking on a nonmoving sidewalk ? Here's how I would approach this problem: if Camille would have walked 51 ft in the time it took to walk 108ft on the moving sidewalk, that means that the sidewalk moved:108-51 = 54ft. 54ft/1.8ft per sec = 30 seconds. SoCamille was walking at a rate of 51 ft/30 seconds = 1.7 feet persecond.
