The sun is 1.5*10^11 METERS from the Earth. In that case it takes approximately 8.3 minutes for sunlight to reach Earth.
t=(1.5*10^11/3.0*10^8)/60=8.33 minutes
If you did want a hypothetical that puts the Earth at 1.5*10^11 kilometers from the sun, then it would take 8333.3 minutes for the sunlight to reach the "Earth's" surface.
t=(1.5*10^14/3.0*10^8)/60=8333.3 minute
