Uncle Ben, in his motor boat, is moving at $8\mathrm{.}92$ m$/$s in the direction in which the waves in the harbour are moving. Each time he passes over a crest, he feels a bump. The bumping frequency is $1\mathrm{.}16$ Hz$,$ and the crests are separated by $5\mathrm{.}05$ m$.$ What is the wave speed in m$/$s$?$

Hint: this problem is tricky! You'll need to remember relative velocity.Uncle Ben, in his motor boat, is moving at $8\mathrm{.}92$ m$/$s in the direction in which the waves in the harbour are moving.
