    In millions it will be 125 million years.

    Step-by-step explanation:

    Due to continental drift, Africa and South America are moving away from each other at a rate of 4 centimeters per year.

    The two coasts are currently separated by 5,000 km.

    distance/rate = time

    5000 km = 500,000,000 cm (1 km = 100,000 cm)

    Time = 500,000,000 cm : 4 cm/year

    = 125,000,000 years

    In millions it will be 125 million years.
