300,000 km/second
One one year's time, light can travel 9.4605284 × 1012 kilometers.
Approximately 300,000 Km/s
Approx 9.46 trillion km.
How many hours does it take to get to 4.5 billion km
300 000 km/s
Light travels at the rate of about 300,000 km a second.
300000 km/second
500 light seconds = 149,896,229 kilometers
At approx 300,000 km per second.
In vacuum it is approx 300,000 km per second.
Light travels at a speed of 300,000 kilometers per second. To convert 57 trillion kilometers to light years, we divide by the speed of light: 57 trillion km / 300,000 km/s = 190 million seconds. Converting this to years, it would take approximately 6 years to travel 57 trillion kilometers in light years.
The information about a light-year is not relevant to answer this particular question. To find out how far light goes (in a vacuum) in any specific time, simply multiply 300,000 (km/second) by the number of seconds.
