Superman can fly at a wide range of speeds depending on the source and context. In many DC Comics portrayals, Superman's flying speed is approximately 7,680 mph (about Mach 10), which is roughly 10 times the speed of sound. However, in other storylines, he can fly much faster—far exceeding the speed of light. For example, Superman has been depicted traveling 11 light-years in just a few minutes, which is thousands of times faster than light speed. In the DC Extended Universe (DCEU) movies, Superman's flying speed has been calculated based on scenes to be around Mach 29 (22,000 mph) up to speeds around Mach 3,462 (over 2.6 million mph) for certain feats such as flying across the Earth or from the fortress of solitude to Africa. Some comic-based calculations even suggest speeds close to 98% of the speed of light (about 660 million mph) or even faster. In summary, Superman's flying speed varies from several thousand mph up to many millions or even approaching the speed of light depending on the particular comic or film representation.
