    The equation you've used is finding time, not distance.

    The equation to use in this case is:

    [tex]v^2 = u^2 + 2as[/tex]

    Where v is the final speed, u is the initial speed, a is the acceleration and s is the displacement.

    Rearrange this to find s.

    Remember that the driver is decelerating, so the acceleration is -2.68 ms^-2.
