Carson Barker · Answer 1

The reason the large jet was seen, but wasn't heard till a few seconds afterwards, is solely because of the speed of light, rather than sound. We know that light is very, very fast. It's faster than sound! That means that answer choices A, B, and D have been eliminated. You now get:

C) The speed of light is faster than the speed of sound.
