Explanation / Answer

According to data , speed of light is 186000miles per second

If there is a mirror in lunar surface then the light comes from it and reaches in earth in 2.6 second

So the distance= velocity of light x time = 186000 x 2.6= 483600 miles

So the distance between moon and earth is 483600 miles
