A fishing boat is lying in the harbour. There is a rope ladder hanging over the side with its end touching the water. The rungs of the ladder are 1 metre apart and the tide is rising at 50 centimetres an hour.

At the end of 6 hours, how many of the rungs will be covered?

None. The boat will rise with the tide.

Well, really. If the boat is rising with the tide - a thing that boats are generally known to do - the ladder will rise, too. There won't be any rungs covered unless a fat dude convention boards the ship during those 6 hours.

Assuming the boat continues to float, none of the rungs will be covered.

If you'd prefer a different answer, I'm sure some ruffians could be persuaded to capsize the whole thing, so that the entire boat and ladder can be found at the bottom of the harbour.

None. The ladder rises and falls at the same speed as the boat. Yes, that does involve mathematics. Not arithmetic, but math is more than arithmetic.

The boat and rungs on the ladder rises and falls as the tide rises and falls.

Trick question.

The boat floats, so none of the rungs will be covered.

And yes, mathematics is the answer. Not sure what the question is, though.
