the boats are 1.5 wave lengths apart ... crest to crest to trough
wavelength = 28 m / 1.5 cycle
frequency = 15 cycles / 1.0 min
wave speed = wavelength * frequency
Two people are fishing from small boats located 28 m apart.Waves pass through the water,
and each person’s boat bobs up and down 15 times in 1.0 min. At a time when one boat is on a
crest, the other one is in a trough, and there is one crest between the two boats. What is the
speed of the waves?
