More generally, a multimodal distribution is a continuous probability distribution with two or more modes, as illustrated in Figure 3.
PAUL NICKLEN'S EMPEROR PENGUIN PHOTOGRAPHY. Penguins would only be able to reach four or nine feet per second otherwise, but they can triple double or triple those speeds with this special bubble boost.
Swimming Speed of the Average Shark. The general rule of thumb is that sharks can cruise at about 5 mph (8 kph), the speed of the fastest Olympic swimmer. If you're just a good swimmer, they have you beat. But often they are swimming around at a slower speed of about 1.5 mph (2.4 kph). But sharks can swim much faster when they are attacking, about 12 mph or 20 kph, the speed of a running human on land. You're not going to be able to swim away fast enough, you'd need a boat or jet ski or some other equipment.
