Answer 1

George flashes a light beam in the direction the train is moving. George measures the speed of light as186,000 miles per second. Tom, a passenger on the train, measures the speed of the light beam.

Answer 2

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
