    Step-by-step explanation:

    Given the formula,

    d = t/3

    Where,

    d is the distance in kilometers

    t is the time elapsed

    = 12 seconds

    d = 12/3

    = 4 km

    Option D. 4 kilometers.

    4.08 km

    Step-by-step explanation:

    we must know what is the speed of sound to determine the distance at which the ray originated

    The speed at which the sound of lightning travels is approximately 0.340km/s

    then

    d = 0.340km/s*12 s = 4.08 km
