speed of light=3×10^8m/s
and we have to find its distance covered in 2nano seconds which is 1ns is equals to a billionth of a second so 2ns will be equal to 2 billionth of a second and can be written as 2×10^-9s

so your answer would be
distance=speed×time
d=3×10^8m/s ×2×10^-9s
d=6×10^-1m (m/s×s so s cancels out)
d=0.6m or 60cm
so interesting fact that any thing so see with your eyes are actually older than you think so clearly you look to past about the billionth or a trillionth of a fraction of seconds
