A fishing boat, with a ladder in it, is leaning against a wall at the harbor. There are 5 oars and 2 fishing nets in the trawler. The distance between two consecutive steps on the ladder is 1 meter. If waves lashing against the wall rise a half meter in every half hour, how long will it take before 6 steps of the ladder are under the waves?
