Answer: The way that goods were distributed throughout Africa was by trade. At first they traded by using camels but since this could not handle humid forest zones a trade point was created known as the Sahel. Then trading cities were developed and this way they created a way to distribute goods throughout Africa. I believe that the best answer is Cities were established that served as distribution centers.
Hope this helps
