44) You are on vacation at the beach. A sailor tells you that he wants to sail his ship away
sometime tomorrow. High tide will occur
at midnight and the depth of the water in
the channel will be 14 then. He also tells
you that at rson, low tide, the depth of the
water in the channel will be 4 feet. "The
problem, he says, "is that I need at least 7
feet of water in the channel or my boat will
hit bottom." What is the latest time that the
sailor can leave, between midnight and
noon, and still get his boat out safely?
