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
