A 5m long fishing boat is anchored on a windy day. The skipper notices that as one wave crest is leaving the stern another is arriving at the bow. If 15 waves are counted arriving in 10s, what is the speed of the water waves?

The wavelength is the length of the boat in this case.
The frequency is 15/10 = 3/2 waves/second
Wave speed = (wavelength)*(frequency)
