$\huge\underline\bold {Answer:-}$

It takes 8 minutes and 20 seconds for the sunlight to reach earth from the sun.

Light travels at a speed of 300,000 kilometres per second. Divide these and you get 500 seconds, or 8 minutes or 20 seconds.

The earth follows an elliptical orbit around the Sun, ranging from 147 million to 152 million kilometre. At its closest point, sunlight only takes 490 seconds to reach Earth and then at the most distant point, it takes 507 seconds for the sunlight to make the journey.
