Question

How many seconds does it take for sunlight to reach the earth

Answer 1

498.67 seconds, wich is 8.31 minutes

Step-by-step explanation:

We can calculate it because we know the distance between the sun and the earth, and the speed at which light travels.

The distance from the sun to the earth is:

`d=149.6 x10^9m`

and the speed of light:

`v=3x10^8m/s`

this the tie it takes for light of the sun to reach earth can be calculated by the next equation:

`t=(d)/(v)`

Substituting the v and d values:

`t=(149.6 x10^9m)/(3x10^8m/s)=498.67s`

This is the anwer: 498.67s

if we want it in minutes we just divide by 60:

`498.67s/60=8.31 minutes`
