How "Fast" is the rate of Light?

Light travels at a constant, finite speed of 186,000 mi/sec. A traveler, moving at the rate of light, would circum-navigate the equator roughly 7.5 time in one second. By comparison, a traveler in a jet aircraft, moving at a ground speed of 500 mph, would certainly cross the continent U.S. As soon as in 4 hours.
