As a statistical average speed gh, yes agreed. But jumping from atom to atom is much faster. For instance, the glowing red from a hot wire is light being generated as thermal heat due to the motion of electrons. That is excited electrons moving decidedly faster than walking pace.
Corrected: Electrons in a copper wire travel at 'less' than the speed of light for example.
In reality, this would be "much less".
Speed of light is 299,792,458 m/s or 1.079 trillion km/h. (trillion is million x million). The solar flares/prominences you see on the sun are gas eruptions that move at roughly 1,000,000km/h. That is fast, but still only 1 millionth the speed of light.
