    Answer:

    2.7%

    Explanation:

    Given:

    Uncertainty of the speedometer (u)= 2.5km/h

    Speed measured at that uncertainty (v) = 92km/h

    Percent uncertainty (p) is given as the ratio of the uncertainty to the speed measured then multiplied by 100%. i.e

    p = \frac{u}{v} * 100%

    p = \frac{2.5}{92} * 100%

    p = 2.7%

    Therefore, the percent uncertainty is 2.7%
