The range finder on the underse camera told her that a grouper started 60 fin strokes ahead of a bull shark. The bull shark made two strokes to every three made by the grouper, but the shark's stroke covered as much distance as the grouper covered in seven strokes. How many strokes did the shark take before it swallowed the grouper? :shock:
