Simple maths Question (part 3)

[TwigtheWonderkid]

A fishing boat is in the harbour. Over the side of the boat hangs a rope ladder, the bottom of which is just touching the water. Rungs of the ladder are a foot apart, the first one being a foot above the water, and the tide rises at 8 inches per hour. After six hours, how many rungs are covered.

Damn, you lot are too smart to be fooled. Amazing how many people say 4, 3 or 5.

yes, very smart.

is the boat floating?

Of course it's floating, it's on the water, with the bottom of the ladder just touching the water. The fact that it's floating is what I hoped would be overlooked.
