A transverse water wave is travelling across the surface of water. As the ball floats on the surface, it moves up and down, but not sideways. At one moment, the ball is at the position illustrated. The wave has a frequency of $0.20\,\text{Hz}$ and an amplitude of $0.70\,\text{m}$. The separation between a trough and a neighbouring peak is $2.4\,\text{m}$. How far does the ball travel in $20\,\text{s}$?
- A$5.6\,\text{m}$
- B$9.6\,\text{m}$
- C$11.2\,\text{m}$
- D$19.2\,\text{m}$
