    d = (max distance / max time) t + 0.

    Step-by-step explanation:

    Earthquake travels 55km of rock in 25 seconds, the relationship between d, the distance traveled in km, and t, the time elapsed in seconds is:

    d = (max distance / max time) t + 0

    d = (55 km / 25 sec) * t

    = 2.2t
