The figure above is a satellite image of the eastern Pacific Ocean and Central America with an overlay over the oceanic crust denoting the age of the seafloor. Each dark gray line that separates two adacent colors (isochrons) represents an interval of 5 million years. The yellow line begins at a location (left) where the age of the seafloor is 0 million years old and ends at a location (right) where the seafloor is 5 million years old. Given that the length of the yellow line underneath the scale bar is the same length of the yellow line on the map, what was the rate of plate motion along the yellow line in millimeters per year (mm/y)?

The figure above is a satellite image of the eastern Pacific Ocean and Central America with an overlay over the oceanic crust denoting the age of the seafloor.
Each dark gray line that separates two adacent colors (isochrons) represents an interval of 5 million years.
The yellow line begins at a location (left) where the age of the seafloor is 0 million years old and ends at a location (right) where the seafloor is 5 million years old.
Given that the length of the yellow line underneath the scale bar is the same length of the yellow line on the map, what was the rate of plate motion along the yellow line in millimeters per year (mm/y)?
