# Two Rungs Make One Write Puzzle - Solution

### The Puzzle:

A ship like the one above (but not much) has a rope ladder hanging over its side. The rungs are 230 mm apart (23 cm). How many rungs will be underwater when the tide has risen one metre?

### Our Solution:

None of the rungs go underwater.

It doesn't matter how far apart the rungs are, or even how much the tide rises, because as the water level goes up, so does the ship, taking the rope ladder with it....
