    Tsunami

    If a tsunami started to the west of Mexico. How long will it take the tsunami, travelling at 200 m/s, to travel 900Km across the Pacific Ocean to reach Japan ?


    Thanks, Chhoeuk

    Thanks, Chhoeuk
    d = vt

    So
    t = d/v = (900 x 1000 m)/(200 m/s) = 4500 s

    (Which is the same as t = 75 min or t = 1.25 hr)
