If the sun approximately 1.5 * 10/11 meters from earth how long does it take for light to reach earth

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

Ithink the answer is b
