Wave Speed Between Two Fishing Boats

Two anglers A and B each sit in a boat on a lake, with the boats $24$ m apart. A train of water waves travels across the surface, making each boat bob up and down 20 times per minute. At one instant boat A is at a crest while boat B is at a trough, and at that moment there is exactly one additional crest between the two boats.

Find the speed of the water waves.
