Simple Relative Velocities

  1. Sep 28, 2005 #1
    If Car A is going 30mi/hr east, and Car B is going 10mi/hr east. What is the relative velocity of Car A to Car B?

    Wouldn't this just be Va - Vb = Vrelative? So.. 30mi/hr - 10mi/hr, the answer would be 20mi/hr?

    Any help, thanks. :smile:

    Concept is right, but there is a mistake in your math.
