Question

The distance between two planets is 1600 km. How much time would the light

signal take to go from one planet to the other?

Answer 1

5.33*10^-3 seconds

Step-by-step explanation:

c = d/t

c = speed of light constant (3.0*10^5 km/s)

d = distance (1600 km)

t = ?

3.0*10^5 = 1600/t

t = 1600/3.0*10^5

t = 5.33*10^-3 seconds

I hope this helped! :)
