This is the fastest form of travel for most snakes, but rattlesnakes donât engage in this style of locomotion often. Rattlesnake speeds have not been specifically measured, but they likely travel at about 2 to 3 miles per hour in very short bursts. In comparison, the fastest humans can run up to 28 miles per hour.
A cheetah can attain speeds up to 76 miles per hour but can only sustain them for over a distance of approximately 1,500 feet. Cheetahs can accelerate at an amazing rate, going from a standstill position to as fast as 68 mph in less than three seconds. cheetah can attain speeds up to 76 miles per hour but can only sustain them for over a distance of approximately 1,500 feet.
