Some sharks are fast and some sharks are slow, but the great majority cruise at very low speeds. While great whites, blues, and makos are capable of a great speed burst, most sharks swim at around 1.5 miles per hour when they're not actively chasing prey or attempting to escape from a dangerous situation.
