A lightyear is the distance that light travels in one year. The speed of light is about 300 million m/s. The earth is about 150 million km from the sun. How long does it take a beam of light to travel from the sun to the earth?​

The distance from the sun to the earth is approximately 150 million km.

To convert this to meters, we can multiply by 1,000 to get 150 billion meters (1 km = 1000 m).

Using the speed of light of 300 million m/s, we can calculate the time it takes for light to travel from the sun to the earth by dividing the distance by the speed of light:

Time = Distance / Speed of light

Time = 150,000,000,000 m / 300,000,000 m/s

Time = 500 seconds

Therefore, it takes about 500 seconds or 8.3 minutes for a beam of light to travel from the sun to the earth.
