The fastest recorded speed achieved by a human-made object is approximately 430,000 miles per hour (700,000 kilometers per hour) by the Parker Solar Probe, which launched in 2018 to study the Sun. In terms of terrestrial speeds, the fastest land vehicle is the ThrustSSC, which reached 763 miles per hour (1,228 kilometers per hour) in 1997. For animals, the peregrine falcon has been recorded diving at speeds of over 240 miles per hour (386 kilometers per hour).
The fastest recorded speed for a human was about 12 m/s. That translates to about 26 miles per hour
The peregrine falcon is renowned for being the fastest bird and one of the fastest animals on the planet, capable of reaching speeds of up to 240 kilometers per hour (about 149 miles per hour) during its characteristic hunting stoop (high-speed dive). In level flight, its speed is significantly lower, typically around 55 to 65 kilometers per hour (34 to 40 miles per hour). This incredible speed makes it an exceptional predator in the avian world.
The garden snail is the fastest land snail. It can travel at a speed of 0.03 miles per hour. Snails are gastropods that move by crawling on a single foot.
The fastest animal on two legs is the ostrich, which can reach speeds of around 40 miles per hour (64 kilometers per hour). Native to Africa, ostriches are flightless birds that have long, powerful legs adapted for running at high speeds to escape predators. Their speed and agility make them the fastest-running birds in the world.
12 mph = 12 * 1760 * 3 / 3600 = 17.6 feet per second
The fastest speed ever achieved on a bike is 183.9 miles per hour (296.009 kilometers per hour).
They are approximately the same speed. (12 mph = 19.312 kilometers per hour).
180 miles per hour
This treadmill's maximum speed is 12 miles per hour. It's lowest speed is 0.1 miles per hour.
50,000 people per hour.
The fastest speed ever achieved on a bicycle is 183.9 miles per hour (296.009 kilometers per hour), set by Denise Mueller-Korenek in 2018.
Usain Bolt run a top speed of 27.3 Miles per Hour.
The speed of Shaun Tait's fastest ball ever bowled in a cricket match is 161.1 kilometers per hour (100.1 miles per hour).
550 million miles per second per hour
The fastest bird is the peregrine falcon, which can reach speeds of over 240 miles per hour (386 kilometers per hour) during its characteristic hunting stoop (high-speed dive). In level flight, the common swift is among the fastest, reaching speeds of around 69 miles per hour (111 kilometers per hour). The peregrine falcon's speed makes it not only the fastest bird but also the fastest animal on the planet.
26 miles per hour is slightly faster because it equates to 41.84 km per hour.
