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 each surface wave on the lake. They count 11 crests that pass by the raft in 21.5 s. Calculate how fast the waves are moving. (Assume the count begins and ends at the top of a crest.)
