to all the people arguing about which tave is third from the top let me ask this - which tave is second from the top? because in my opinion, looking at the diagram in question, the second tave from the top is number 9. which would make the third from the top number 8.

Ship Ladder - Back to the Logic Puzzles
A ship anchored in a port has a ladder (beginning and ending with a tave), where the bottom tave touches the water. The distance between taves is 20 cm and the length of the ladder is 180 cm. The tide is rising at the speed of 15 cm each hour.
When will the water be on the third tave from the top?

Spoiler for Solution

Time to get a new ladder.

Ship is anchored to the sea bed. One assumption only- no slack in the anchor.
6 intervals from the initial water line to the third tave- times 20 cm = 120 cm- that divided by 15/cm per hour is 8 hours until the third tave is reached.

what is a tave?

funny - this word has been bugging me for ages - so far as it is not on google as far as I am able to see.
Why not PM admin if you really need to clarify, or put it in as a topic.
Not in my old oxford dictionary either!

So with a Rung at the top and bottom - I have 10 rungs/taves. The third rung from the top is 60 cm down. Therefore the water needs to come up 120 cm. Rising at 15 cm/hr... I get 8 hours.
The only "sticky" part I felt was determining 3rd from the top. So I felt the top was the top. Counting 3 down from there... with 20 cm between each.
