    If the true speed is 60, then it would be 0 ≤ (V1 - 60) ≤ 10?

    So the displayed speed must be more than 60 but less than 70, but the difference between true and displayed also cannot be zero? So a displayed speed of 1 above the true speed would satisfy the law?

    Just curious, I have already answered my original thought which was about tachos.

    The difference might not be bigger than 10 and not smaller than 0. Thus any indicated speed from 60 to 70 included is legal.

    In other words, it can show a bit more, but never anything less than you are actually going. Useful when a few different tyre sizes are approved for same car, the speedometer shows a bit different values then.

    Yes.
    So the displayed speed must be more or equal than 60 but less or equal than 70,
    Corrected above.
    but the difference between true and displayed also cannot be zero?
    No, why.
    It can be zero.

    It would, same as displayed speed exact same as real speed.
    Just curious, I have already answered my original thought which was about tachos.

    In short in your example, when car is doing 60km/h, speedomoter can show 60km/h or 70km/h or anything in between.
