Answer:
distance = 1.5x10^11m
velocity = 3.0x10^8 m/s
Substituting into the equation:
time = (1.5x10^11m)/( 3.0x10^8 m/s) = 500 seconds
Therefore, light travelling at 3.0x10^8 meters per second takes 500 seconds (8 minutes, 20 seconds) to reach the Earth, which is 1.5x10^11 meters away from the sun.
