now, it takes 1 second for light to travel 300,000,000 meters.
if we know it takes light 1 second to go 300 million meters, then in 365 days or a year, or 60*60*24*365 seconds, it will then travels
300,000,000 * 60 * 60 * 24 * 365 meters in 1 year,
how about in 110,000 years, how many meters has it travelled?
300,000,000 * 60 * 60 * 24 * 365 * 110,000 that many meters.
we know she travels the Milky Way in 110,000 years or 60 * 60 * 24 * 365 * 110,000 seconds
and we know that 110,000 years is 3468960000000 seconds, so
if it travels 300000000 meters in only 1 second, in 3468960000000 seconds, it will travel then (300000000) * (3468960000000) meters
or 1040688000000000000000 meters.
