Let me pull out the information you need for you:

every 0.8 seconds, a new wave is created (when the water is struck at point X).
There are 2 diagrams, 1 diagram is 1 second after the first.

In the first diagram, Q has travelled 2.0cm from X.
In the second diagram, a new wave (not Q) has travelled 3.5cm from X.

We know this new wave was created 0.8s after Q was created.

We also know that if the diagram was exactly 0.8 s (not 1s) after the first, this new wave would have travelled 2.0cm from X, just like Q did.

The fact that the diagram is at 1s and not 0.8s has revealed something important about the wave which we can work out.

Thanks for your help. Got the answer correct (6cm)
