How Fast Is The Flash? (According To Math)

The speed of the Flash depends on the writer’s imagination and his writing, but it is considerably faster than the speed of sound (Mach 1).

In the comic Justice League of America, Ep #89, when a fictional nuclear bomb was set off in Korea, he saved 532,000 people. It took the Flash 0.00001 microseconds to save every person, and the Flash traveled 70 miles each time he carried someone to simplify this.

In fact, even if he carried two people on specific rounds, we can say that he traveled 354,667 times, at 0.00001 microseconds. To accomplish this mission, the Flash would have traveled at 2.5 quintillion Miles Per Second.

The Millennium Falcon speed in hyperspace is impressive, and it travels at an intergalactic speed of 1050 km/h. In contrast, the Flash outruns it by a big margin because its top speed is rated at 17 Mach.

Superman Vs. The Flash:

In theory, the Flash can easily beat Superman by a considerable margin. The fact is that the Flash is faster than light speed and much faster than Superman.

Godspeed Vs. The Flash:

Even though Godspeed is a villain, entering the Speed Force allows him to run up to 10 times the speed of light, meaning he can easily beat the Flash in terms of speed.
