Is light faster than a second?

Light travels approximately 1 foot per nanosecond or 186 miles per millisecond or 300,000 kilometers per second. Light from distant objects such as stars can take millions of years to make the journey to our eyes so that we see them as they were in the distant past rather than how they are right now.
