Answer:
The distance of a star from the earth is
8.33 light minutes means that
it takes 8.33 minutes for light to reach the earth
from the ultimate source of light -
the Sun. The distance is large, hence light year is used.
Speed of light = 3×108ms−1
Time = 8.33 min = 499.8s
Distance = speed × time
=3×108×499.8
=1.5×1011m
