A person is walking with constant speed vW , with respect to a moving sidewalk at O'Hare. He is walking in the same direction as the moving sidewalk which has speed vMS with respect to the stationary floor of O'Hare. The time it takes him to walk the length D of the moving sidewalk is tForward . For some unknown reason, once he gets off the moving sidewalk, he turns around and walks in the opposite direction of the moving sidewalk at that same constant speed vW , with respect to the moving sidewalk, until he finally exits the moving sidewalk at his original entrance. The time it takes him to walk the length of the moving sidewalk on this return leg is tBack
1) What is tForward in terms of vW, vMS, and D, as needed?
2) What is tBack in terms of vW, vMS, and D, as needed?
3) Assuming vW = 1.5 m/s, tForward = 40 s, and tBack = 125 s, what is vMS, the speed of the moving sidewalk with respecto the stationary floor?
4) Once again, assuming vW = 1.5 m/s, tForward = 40 s, and tBack = 125 s, what is D, the length of the moving sidewalk?

03.4 When walking on a moving sidewalk in the same direction the sidewalk is moving, you take 24 s to go the length of the sidewalk. When walking on the sidewalk in the opposite direction to its motion, you take 36 s to return to your starting point. Your walking speed on fixed ground is 1.5 m/s. How long is the moving sidewalk and how fast is it moving?

A moving sidewalk in an airport moves people between gates. It takes Jason's 5-year-old daughter Josie 28 sec to travel 112 ft walking with the sidewalk. It takes her 27 sec to walk 54 ft against the moving sidewalk in the opposite direction). Find the speed of the sidewalk and find Josie's speed walking on a non-moving ground. Part 1 out of 2 The sidewalk moves at ft/sec.

A young boy called Nick is stranded at the airport with his father, Tom, because of bad weather. To pass the time, they decide to have a race. The race is an out-and-back race, starting and ending at the same place. Tom runs at constant speed a distance L, and then turns around and comes back. Nick, because he is so young, gets an advantage: while running away from the start line, he...
