    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
    V=f(3)
    =(.769)(3)
    =2.31 ] and that was wrong

    Please advise me as to where my mistake is.
