3 seconds of light in vacuum means a distance of 899377374 m. 100 seconds of sound in air of a temperature of 20°C or 68°F means a distance of 34300 m. Light covers a much longer distance.
Light seconds is a distance not a time.
A light second is a unit of distance, not a unit of time.
In space or in air, light covers about 186,000 miles (300,000 km) every second."Light year" is a distance ... the distance light covers in a year, at that speed.
The average distance from the Earth to the Moon is about 1.28 light-seconds. This means it takes light about 1.28 seconds to travel from the Earth to the Moon.
distance = speed x time. Multiply the speed of light (in miles/second in this case) by the time in seconds, to get the distance travel in miles.
Light-minutes is a distance, not an amount of time.
Approximately 1.28 light seconds away from Earth is the Moon. The average distance between Earth and the Moon is about 1.28 light seconds.
The distance to the moon is about 1.3 light seconds or about 0.000000032 light years.

Light. Since the speed of light is almost a million times the speed of sound (in air), it's hardly necessary to do lots of calculations to get this answer.Update: the number of seconds is actually irrelevant. To know how fast something goes, you only need the speed.
The distance from the sun to the Earth is about 150 million kilometers. To convert this to meters, we multiply by 1000 to get 150 billion meters.
A light-second is the distance that light travels in a second, i.e., 300,000 kilometers.
