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?

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
