Over each season, The Flash’s top speed has expanded, as now the old benchmark established in Season 2, Episode 18, “Versus Zoom” of Mach 13 has been exceeded. Converted to miles per hour, Mach 13 is 9,974.5 miles, which is hypersonic speed and sounds impressive, but that’s still under the current mark of the fastest humans have traveled. 2500 Miles per hour = 3.7279×10-6 Speed of light: 2 Miles per hour = 2.982×10-9 Speed of light: 20 Miles per hour = 2.9823×10-8 Speed of light: 5000 Miles per hour = 7.4558×10-6 Speed of light: 3 Miles per hour = 4.473×10-9 Speed of light: 30 Miles per hour = 4.4735×10-8 Speed of light: 10000 Miles per hour = 1.5×10-5 Speed of light Zoom, Black Flash, Savitar, Flash so many speedsters but who is the fastest CW of all?My own list what I think :D Superhuman Speed: Professor Zoom is able to move and travel at super human speeds. He can travel up to speeds of 7,500,000 mph., deliver hundreds of blows a second, walk on water, create cyclones and vibrate his molecules super fast to pass through solid objects. These big cats are the fastest land animals and are capable of running at a top speed of 60 to 70 mph (96 to 112 km/h). One cheetah from the Cincinnati Zoo named Sarah was recorded running the 100 A bullet from a 9mm Luger handgun, by comparison, would cover half that distance at speeds of up to 1,360 mph (2,200 km/h). Something like an AK-47, among the most common firearms in the world 9ofuqSa.
