A motor launch purchased with the aid of a term loan sanctioned by the branch under its inland sheries scheme plies upon a river in which the current runs at a steady rate. The speed of the launch in still water is 12 kilometres an hour and the speed of the current is 4 kilometres an hour. The launch set out from its moorings, ran downstream to a landing place lower down the river, and returned at once to the moorings from which it had started, the whole of the outing having occupied 12 hours of running time. What is the distance of the landing place from the moorings of the launch?
