Periodic waves spread out over the surface of a lake where two women, Jenny and Melissa, are fishing in separate boats 65 meters apart. Each woman's boat bobs up and down 19/min. At a time when Jenny's boat is at a crest, Melissa's boat is at its lowest point, and there are 4 additional crests between them. Calculate the wavelength of these water waves.

And what is the speed of these water waves?

A group of swimmers is resting in the sun on an off shore raft. They estimate that 1.1m separates a trough and an adjacent crest of surface waves on the lake. In addition, they count 23 crests that pass by the raft in 15.7seconds.
