If the Atlantic Ocean is widening at a rate of 3 cm per year how far (in kilometers) will it spread in a million years?

To compute the rate of spread, we must first take into account the constant values.

Rate of Spread = 3 centimeter per year

Now, we multiply 3 centimeters to 1 million years. Or,

Rate = 3 centimeter x 1,000,000 years

         =  3,000,000 centimeters

Now, we find the kilometer equivalent for 3 million centimeters.

3,000,000 centimeters = 30 kilometers

Thus, after 1 million years, the Atlantic Ocean will spread at least 30 kilometers.
