Just quick one....

"A ladder hangs over the side of a ship anchored in a port. The bottom rung touches the water. The distance between rungs is 20 cm and the length of the ladder is 180 cm. The tide is rising at the rate of 15 cm each hour.

When will the water reach the seventh rung from the top?"

Well, Philip, there is another scenario. Perhaps the time of the anchored ship is bang in the middle of ice-cap melting due to severe global warming, and, also assuming that the ship is abandoned, then it will continue to rise with the water level until it has reached the end of the length of the anchor. At that point, the ship will no longer be able to rise with the water and so the sea will begin to swallow the rungs until the seventh is breached. Sure, it may take decades or centuries, but the point is that it IS possible that the sea can cover the ladder rungs - that is, if the ship hasn't rusted by that time.

As the water rises so does the ship with the ladder. Therefore the water will never reach the seventh rung from the top.

Grannyb Clever lady.
