It is impossible to derive an answer from the information provided. At first glance it would appear that the answer would be 500 years; in actuality, the sediments that created the sedimentary rock would have been substantially compressed during the lithification process, resulting in a rock thickness that was less than the initial sediment thickness, depending on the type of sediment.
