Just FYI, The circumference of earth is roughly 4 * 10^7 metres, and the speed of light is 3 * 10^8 m/s, so light can actually circle the globe almost 7.5 times per second.
The depths of the oceans are just a few milliseconds away (40ms -ish?).
I was going for the distance from some arbitrary spot in North America to some arbitrary spot way out in the middle of the Pacific Ocean, where I'd assume the ocean is at its deepest, but this is interesting too.
