    Riddle me this.
    A boat is moored to a pier with a ladder hanging over the side and into the water. The rungs on the ladder are spaced 12 inches apart, and 4 rungs are visible above the waterline. It is 3:30 PM and the tide is rising at a rate of 5 inches per hour. How many rungs will be visible at 10:15 PM?

    Four - the boat would rise with the tide. The same number of steps would always be visible.
