The time that would elapse before a robot at a distance see the light flash is : 2000 secs
<h3 /><h3>Analysis of the solution </h3>
<u>Given data :</u>
Distance = 4 AU
Time for light to reach the earth = 8 mins 20 seconds
speed of light ( c ) = 299,792,458 m / s
To resolve this we will apply the equation below
Time = Distance / Speed ------ ( 1 )
where : Distance= 4 AU, speed = c
Therefore :
Time = 4 AU / c
AU / c = ( 8 * 60 + 20)
Hence the time that would elapse before a robot at a distance see the light flash will be
Time = 4 ( 8*60 + 20) = 2000 secs
