# the distance from the sun to earth is about 1.5x10^11 meters. suppose light travels at a speed of 3x10^8 meters per second. About how long does it take light from the sun to reach earth? PLEASE HELP!!!

## Since Speed=Distance/Time

Therefore Time=Distance/Speed
=1.5 x 10^11m/3 x 10^8ms^-1
=500 seconds.

## time = distance/speed, so it takes

1.5x10^11 / 3x10^8 = 0.5x10^3 seconds

We all know it takes light about 8 minutes (480 seconds) to reach the earth. .5x10^3 = 500 is pretty close.

## 1.5 x 10^11 / 3 x 10^8

Divide 1.5 by 3.
Subtract the exponents.
Change your answer to scientific notation (move the decimal in 0.5 x 10^3)
5 x 10^2

## Well, it's a good thing that I, the Clown Bot, am here to help you with your scientific question! Now, let's calculate the time it takes for light to travel from the Sun to Earth.

Given that the distance between the Sun and Earth is about 1.5x10^11 meters and the speed of light is 3x10^8 meters per second, we can use the formula:

Time = Distance / Speed

Plugging in the values, we get:

Time = (1.5x10^11 meters) / (3x10^8 meters per second)

Now, let me just do some pesky calculations here... *beep boop beep*

Ah, here we go! The time it takes for light to travel from the Sun to Earth is approximately 500 seconds.

So, to answer your question, it takes light about 500 seconds, or around 8 minutes and 20 seconds, to reach Earth from the Sun. Just enough time for a quick coffee break, don't you think?

## To find out how long it takes for light to reach Earth from the Sun, we can divide the distance between them by the speed of light.

The distance from the Sun to Earth is approximately 1.5x10^11 meters, and the speed of light is 3x10^8 meters per second.

To calculate the time it takes, we divide the distance by the speed:

Time = Distance / Speed

Time = (1.5x10^11 meters) / (3x10^8 meters per second)

To perform this calculation, we can simplify the numbers:

Time = (1.5 / 3) x (10^11 / 10^8) seconds

Time = 0.5 x 10^3 seconds

Time = 500 seconds

Therefore, it takes approximately 500 seconds for light to travel from the Sun to Earth.

It is important to note that the values used in this calculation are approximate. The actual time may vary slightly due to various factors.
