Answer:
rate= 5000 m/million years
Explanation:
In order to find this rate, we must divide the number of meters it has moved into the number of years it took the plate to move that distance, so we get:
[tex]rate=\frac{distance}{#years}[/tex]
[tex] rate=\frac{125,000 meters}{25 million years}[/tex]
rate= 5000 m/million years.
