Last one was – NEITHER, EGG YOLKS ARE YELLOW!    Did you get it..

So when Josh isn’t fitting underfloor heating or laying our liquid screed he enjoys doing up boats. I’m feeling chuffed as we got him stumped on this one!

A 10’ rope ladder hangs over the side of a boat. 

The bottom rung is on the surface of the water. 

The rungs are one foot apart, and the tide goes up at the rate of 6” per hour.

How long will it be until three rungs are covered?
