After being irradiated with Isotope E, Quicksilver managed to speed faster than sound. In small distances, the comparison of speed of sound and light is almost useless.

Just try to compare the delay of the sound of a clap to when it was made 2 meters from you, useless, right?

And as I already said, Hulk would still be able to surpass Superman's strenght, after all Hulk's strenght is actually incalculable.
