Answer:
384,000
Step-by-step explanation:
Time taken by light to travel from earth to moon t=1.28s
Let us assume that the speed of light = c
So, the distance traveled by light in this time = c x t
this will be the distance which light traveled to reach moon, so this will be the distance between earth and moon.
The speed of light is 300000 km/s
By putting the values
we get
Distance = c x t
= 300000 x 1.28 km
=384000 km
