Answer:
v = 2.85 m/s
Step-by-step explanation:
Given that,
A skipper on a boat notices wave crests passing his anchor chain every 5.6 s.
The distance between wave crests to be 16 m.
We need to find the speed of the waves. The speed of a wave can be calculated by the formula as follows :
![v=f\lambda\\\\v=(\lambda)/(T)\\\\v=(16)/(5.6)\\\\v=2.85\ m/s](https://img.qammunity.org/2022/formulas/physics/high-school/p94egxg68y7n28eo05lb2o1l55w8xbsp06.png)
So, the speed of the wave is 2.85 m/s.
