So, for my particular problem would the multiplication be:
3 cm/1 yr x 1 km/100 cm?
Resulting in an answer of 300 years?
or, would it be 3 cm/1 yr x 1km/100,000 cm
Resulting in an answer of 300,000 years?
Any help would be much appreciated with this problem.
The problem is: The rate of plate movement along portions of the Mid-Atlantic Ridge has been determined to be 3 cm/yr. At this rate how long will it take the Atlantic Ocean to widen another one kilometer?
