I don't understand why velocity is positive here?

  1. Feb 9, 2016 #1
    1. The problem statement, all variables and given/known data

    It says that a horse gallops 116m away from its trainer in 14.0s and then abruptly turns and gallops halfway back in 4.8s.

    I need to calculate average velocity . displacement/ time elapsed. displacement is xf-xi.

    2. Relevant equations
    avg velocity= displacement/ time elapsed

    displacement = xf-xi

    3. The attempt at a solution
    Shouldn't it be (58-116)/18.8? the solutions manual says its 116-58/18.8...why?

    Nevermind, it's a dumb question I got it. xi does not equal to 116, it's equal to zero.
