In 2009 Jamaican sprinter Usain Bolt set the world record in the 100-meter sprint at 9.58 seconds. For those of us more accustomed to sitting than sprinting, to translate this feat into terms of speed is to simply underscore the stunning nature of Bolt’s performance.
Speed is the rate at which an object (or person) moves through time. It is represented mathematically as speed = d/t (in which d is distance and t is time). That means that Bolt’s speed during his world-record run was 10.44 meters per second. Since many people are more familiar with automobiles and speed limits, it might be more useful to think of this in terms of kilometers per hour or miles per hour: 37.58 or 23.35, respectively. That’s faster than the estimated average traffic speed for the U.S. cities of Boston, New York City, and San Francisco. Even more astounding is the fact that Bolt started from a speed of zero and then had to accelerate, which means that his top speed actually was faster.
In 2011 Belgian scientists used lasers to measure Bolt’s performance in the different stages of a 100-meter race held in September that year. They found that, 67.13 meters into the race, Bolt reached a top speed of 43.99 kilometers per hour (27.33 miles per hour). He finished with a time of 9.76 seconds in that race, but research has suggested that, with his body type, he probably shouldn’t even be competitive at that distance. From a biomechanical perspective, the fastest sprinters are relatively short, and their muscles are loaded with fast-twitch fibers for rapid acceleration. The elite sprinter is a compact athlete, not a tall and lean one. Given his size—literally head and shoulders above the other competitors—Bolt should be last off the blocks and last across the finish line. And yet he is the fastest man in the world.
The fastest top speed ever achieved by a human was Bolt's 12.42 meters/second (27.8 mph). In the fastest race in history, Usain Bolt
Usain Bolt
Usain St. Leo Bolt OJ CD OLY (/ˈjuːseɪn/; born 21 August 1986) is a retired Jamaican sprinter, widely considered to be the greatest sprinter of all time. He is an eight-time Olympic gold medalist and the world record holder in the 100 metres, 200 metres, and 4 × 100 metres relay.
ran 100 meters in 9.58 seconds, defeating Tyson Gay who finished second in 9.71 and Asafa Powell who finished third, to become the fastest human in world history.
Usain Bolt. The Jamaican sprinter is the fastest human alive, our reality's version of the Flash. He set a world record in 2009 at the 100 meter sprint at 9.58 seconds. His top speed was 27 mph.
Scientists say that the human frame is built to handle running speeds up to 40 miles per hour. The only limiting factor is not how much brute force is required to push off the ground, as previously thought, but how fast our muscle fibers can contract to ramp up that force.
The Space Shuttle has an orbital velocity of around 30,000km/h, but the crew of Apollo 10 hold the official record for the fasted manned vehicle when they reached 39,897km/h relative to the Earth on 26 May 1969 during their return from lunar orbit.
From this data, we can calculate the average human athlete sprinting speed across both sexes to be 18.23 mph (3:17.5 minutes per mile), or 29.33 kilometers per hour. Average male sprinting speed: 19.52 mph (3:04.4 minutes per mile), or 31.4 kilometers per hour.
To date, the fastest a human has been recorded running is Usain Bolt's 2009 record-smashing 100-meter dash. There, he briefly reached a top running speed of 27.78 mph.
The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom, with a diving speed of over 300 km/h (190 mph). The fastest land animal is the cheetah. Among the fastest animals in the sea is the black marlin, with uncertain and conflicting reports of recorded speeds.
Obviously, the cheetah wins the race comfortably, clocking in a time of 5.95 seconds, reaching speeds of up to 75 miles per hour or 120 kilometres per hour. Even Usain can't live with that raw pace. At the time of his record, he reached speeds of 27.8 miles per hour, or 44.7 kilometres per hour.

For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).
The men's world record is 9.58 seconds, set by Jamaica's Usain Bolt in 2009, while the women's world record is 10.49 seconds set by American Florence Griffith-Joyner in 1988.
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
Despite Letsile Tebogo and Noah Lyles achieving impressive top speeds—Tebogo reaching 27.92 mph and Lyles 27.84 mph -- neither was able to break Usain Bolt's world record of 9.58 seconds. The key reason lies not just in speed but in the combination of acceleration, stride efficiency, and race strategy.
Regular runners usually aim for a turnover rate of about 180 steps per minute. So, a super fast sprinter would potentially set a seemingly impossible speed by utilizing a greatly accelerated turnover, coupled with strong leg pushoffs for optimal forward propulsion. 60 mph is impossible for a human.
The first ever person to break Mach 1 and to break the sound barrier was Chuck Yeager in 1947. And the highest Mach number ever reached was 9.6 achieved by the NASA X-43 in 2004, an experimental unmanned hypersonic aircraft. The highest Mach number ever reached in a manned aircraft was Mach 6.7, achieved by William J.
