Pepe and Alfredo are resting on an offshore raft after a swim. They estimate that 3.0 m separates a trough and an adjacent crest of surface waves on the lake. They count 15 crests that pass by the raft in 19.5 s. Calculate how fast the waves are moving.
[I tried saying that frequency= 15/19.5=.769
=2.31 ] and that was wrong

Please see the attached file for detailed solution.
Yes, you are correct ...
Supplemented with graph, the solution shows detailed calculation of the speed of a wave.
