How many minutes it takes light from there sun to reach the earth?

With the simple equation: Rate*Time=Distance. Since you need to find the time it would be: Time=Distance/Rate. The sun is approximately 93 million miles from the Earth and the speed of light is approximately 186000 miles per second. So you would take 93000000/186000, which equals 500. It takes about 500 seconds(around 8 minutes) for the Sun's light to reach Earth.
