The speed of light is approximately 300,000 km/s. To calculate the distance that light can cover in one year (which is known as a light year), we need to first calculate how many seconds are in a year.
1 year = 365 days * 24 hours * 60 minutes * 60 seconds
1 year = 31,536,000 seconds
Now, we can calculate the distance of a light year:
Distance = Speed * Time
Distance = 300,000 km/s * 31,536,000 seconds
Distance = 9.461 × 10^12 km
Therefore, one light year is approximately equal to 9.461 trillion kilometers.
