    Answer:

    52.7 m

    Explanation:

    Given that

    speed of the vehicle, v = 95 km/h

    time of inattentiveness, t = 2 s

    distance travelled, s = ?

    Since we have the speed in km/h and the time in s, it would be best if we converted one of them to make sure we have all units in the same rank.

    95 km/h = 95 * 1000/3600 m/s

    95 km/h = 95000/3600 m/s

    95 km/h = 26.38 m/s

    Now, we use our derived speed in m/s

    Speed of a moving vehicle is given by,

    v = s/t, where

    v = speed in m/s

    s = distance travelled, in m

    t = time spent, in s

    if we make d the subject of formula by rearranging the equation, we have

    s = v * t

    distance travelled, s = 26.38 * 2

    distance travelled, s = 52.7 m

    therefore, during this inattentive period, 52.7 m was travelled.
