PhyFl18-2.5.5 I the speed of light is about a million times faster than the speed of sound. That is why you see the lightning and then hear the thunder 5 seconds later if the lightning was a mile away. (since speed of sound is about 1100 ft/sec which is about a mile every 5 seconds. Still, that’s pretty daggone fast. I wish I could go a mile in 5 seconds. That would give me a lot more time at home at lunch. Just sayin.
