A ladder hangs over the side of a ship anchored in a port.The ladder has 10 rungs. 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,
How long will it take the water reach the seventh rung from the top?
PM answers please.
