Do you think you are a fast runner? Tim Montgomery beat the man's 100 m world record with an astonishing run of 9.78 seconds in 2003. His speed reaches over 40km/h! The fastest land animal is the cheetah, which can reach 110 km/h over a short distance. The fastest bird is the peregrine falcon, which can speed up to 320 km/h in a dive! Even more amazing, Andy Green drove his jet-engine car up to 1,300 km/h in 1997! However, all these are considered slow by light speed. Light travels at almost 300,000 km/h in space! Now, that is real fast!
