Historical Math Question
Two rats started digging into a 50cm thick wall on opposite sides. On the first day, each rat dug 10cm into the wall. Subsequently, the depth of the hole dug by the bigger rate doubled each day while the depth of the hole dug by the smaller rat decreased by half each day. The two rats met a few days later. What was the depth of the hole into the wall did each rat dug?
