Two walkers set out from point A toward point B at the same time. When the first one had reached the half of the distance, there were a 24 km way to finish for the second walker. When the second walker had reached the half of the way, there were a 15 km way to finish for the first walker. How many kilometers should the second one walk to the finish when the first one will have done the way?
