Question 62984
speed of light = 3 x 10^8 m per sec.

Distance to be traveled = 149 x 10^9 m

Time taken = distance/speed

           = (149 x 10^9)/ (3 x 10^8)

           = 49.7 x 10

           = 497 sec.

          = 8.28 min

It takes approximately 8.28 min for light to reach earth.


Good Luck!!!
