Answer:
Sunlight travels at the speed of light. Photons emitted from the surface of the Sun need to travel across the vacuum of space to reach our eyes. The short answer is that it takes sunlight an average of 8 minutes and 20 seconds to travel from the Sun to the Earth. ... Light moves at 300,000 kilometers/second.

300000/sec
1min = 60 sec
8min = 480 sec
300000 × 480 = 144000000 km
the distance between sun and earth is 144000000km . that is a long way to go
