While sitting in your canoe, you encounter a wave disturbance created by a passing motor boat. Your canoe bobs up and down once every 2.5 s and the average distance between the wave crest moving your boat is 3.6 m. How fast is the wave moving?

The wave period is T = 5 sec as up and down is the time t = 2.5 s between the two extremes, crest and trough, and that's 1/2 wave length. And L = 3.6 m is the length.
So the wave is traveling V = L/T = 3.6/5 = .72 m/s. ANS..
