Relative Velocity moving sidewalk

  1. Sep 11, 2015 #1
    1. The problem statement, all variables and given/known data
    A "moving sidewalk" at an airport moves at 1.5m/s and is 12 m long. A person enters the sidewalk and walks at 1.8 m/s relative to the sidewalk.
    A)How much time is required for the person to reach the opposite end if the person walks in the same direction as the sidewalk is moving?
    B) How much time is required for the person to reach the opposite end if the person walks in the opposite direction?


    The attempt at a solution
    Sorry! My professor didn't really explain how to do this so I'm stuck on this problem. Thanks!

    Make an attempt.
    What formulae might you be able to use, if you're calculating duration, given distance and speed?
