    v = average speed of movement of the Southwest Indian Ridge = 20 mm/year

    d = distance moved by the Southwest Indian Ridge = 100 mm

    t = number of years required to move distance "d"

    distance traveled is given as

    d = v t

    inserting the above values in the formula

    100 mm = (20 mm/year) t

    dividing both side by 20 mm/year

    t = 100 mm / (20 mm/year)

    t = 5 years
