A ship anchored in a port has a ladder which hangs over the side. The length of the ladder is 200cm, the distance between each rung is 20cm, and the bottom rung touches the water. The tide rises at a rate of 10cm an hour. When will the water reach the fifth rung?
Answer Never
Gotcha! This is a trick question. As the tide rises, the boat will also rise, and the water will never go above the bottom of the ladder. Sorry if you were stumped, but make sure to remember to think outside the box - or the boat, as it were.
