The airport terminal in Geneva, Switzerland has a "moving sidewalk" to speed passengers through a corridor. Peter who walks through the corridor, does not use the moving sidewalk, and takes 150s to do so. Paul who simply stands on the moving sidewalk covers the same distance in 70s. Mary not only uses the sidewalk but alson walks along it. Assume that Mary and Peter walk at the same speed. How long does Mary take?
