Here's a question for the day-- what's faster: a shark, a waterfall, or a motorcycle? Let's deal with maximums. Sharks come in third place, with the shortfin mako shark having recorded speeds of up to 74 km/h. The top speed of water in a waterfall would depend on height-- the world's tallest waterfall is Angel Falls, at 979 meters. Theoretically, water would be falling at almost 500 km/h by the time it reached the bottom. Motorcycles ultimately take the speed prize, with a world record of 605 km/h.
