Faster than a speeding bullet. More powerful than a locomotive. Able to leap tall buildings in a single bound. Look, up in the sky! It’s a bird! It’s a plane! It’s Superman! Yes, it’s Superman, a strange visitor from another planet who came to earth with powers and abilities far beyond those of mortal men. Superman, who can change the course of mighty rivers, bend steel with his bare hands, and who, disguised as Clark Kent, a mild-mannered reporter for a great metropolitan newspaper, fights a never-ending battle for truth, justice, and the American way.

But how fast can he run? Faster than me, that's for sure!

I guess maybe he can both fly and run faster than a speeding bullet.

So how fast does a bullet speed? I guess it depends on the gun, right?
