Physics

A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.90 s for the boat to travel from its highest point to its lowest, a total distance of 0.640 m. The fisherman sees that the wave crests are spaced 7.60 m apart.

How fast are the waves traveling?
v= x m/s

  1. Isn't the period twice 2.9 seconds?

    frequency*wavelength=speed

    and freq=1/period
