Because distance/time = the speed at which something travels.
A light-minute is a measure of distance, not time. A light-minute is the distance light travels in a vacuum in one minute. Approximately 11,160,000 miles (18,000,000 km)

(distance the car travels) divided by (time it takes to cover that distance)
Speed = Distance / Time
Light travels approximately 1 micron in 3.3 femtoseconds.
You FIRST see it, then you HEAR it. The time delay depends on your distance from the source of the explosion. The explanation, light travels faster than sound.
That's aproximately the distance sound travels in one second, in air. Since light travels at a speed of 300,000 kilometers per second, the answer is, approximately 300,000 kilometers.
"Light year" is a distance. Specifically, it's the distance that light travels through vacuum in one year. The distance is approximately 5,878,291,000,000 miles.
A light-minute is the distance light travels in a vacuum in one minute's time. The distance of a light-minute is 11,176,943.8 miles or 17,987,547.5 km
Sound travels at approximately 343 meters per second in air at room temperature. So, in this scenario, it would take approximately 3 seconds for the sound of the explosion to reach you since you are 1020 meters away.
The mean distance of the Sun from the Earth is approximately 149,600,000 kilometers, or 92,960,000 miles, and its light travels this distance in 8 minutes and 19 seconds
That is short for "light-year" - the distance light travels in a year. Approximately 9.5 million million kilometers.
The distance of the Sun from the Earth is approximately 149,600,000 kilometers, or 92,960,000 miles, and its light travels this distance in 8 minutes and 19 seconds.
An observer sees an explosion before hearing it because light travels much faster than sound. Light travels at approximately 299,792 kilometers per second (about 186,282 miles per second), while sound travels at about 343 meters per second (around 1,125 feet per second) in air. This significant difference in speeds means that the light from the explosion reaches the observer almost instantly, while the sound takes longer to arrive. As a result, there's a noticeable delay between seeing the explosion and hearing it.
2.5902 x 1010 kilometers (1.6095 x 1010 miles) (rounded)
Light travels at a speed of approximately 30 centimeters per picosecond in a vacuum.
