Speed of light = 186000 miles per second.
Distance from Sun to Earth averages 93000000 miles.
Distance from Earth to Moon averages 238897 miles.
Therefore light from the sun takes - on average - :
(93000000/186000) = 500 seconds (8 minutes, 20 seconds)
to reach the earth.
Light from traveling from earth to moon will take - on average -:
(238897/186000) = 1.28 seconds.
If the moon is closer to the sun than the earth is, light from sun to moon will take 500 - 1.28 = 498.72 seconds. If the moon is further away than the earth, it will take 500 + 1.28 = 501.28 seconds.

It takes roughly 8 minutes for light from the sun to reach the earth. Since the moon is only about 400,000 miles away, it would take light about an extra second to reach the moon, possibly less depending on where it is in its orbit.

it takes light from the sun 8.4 to get from the sun to the earth. Light travels at about 186,282.397 miles/sec, and the moon is about 238,854 miles away from the earth, so thats just over a second of difference between the two, but also depending on where the moon is at the time. I would think 8.4 minutes is close enough

distance = rate * time, look up the distance from Sun to the Moon, and look up the speed of light. Then solve the equation for time
time = distance / rate

7 min aprox. distance/speed of light=time
