Figure shows the relation between the age of the oldest sediment, in millions of years, and the distance, in kilometers, at which the sediment was found from a particular ocean ridge. Seafloor material is extruded from this ridge and moves away from it at approximately uniform speed. Find the speed, in centimeters per year, at which this material recedes from the ridge,
