The speed of light is 299212.5984 [tex]\frac{km}{s}[/tex] (kilometers per second), if the  light 1.27 seconds to travel from Earth to the moon. If the distance is  380,000 km to the moon.

Explanation:

The given is,

                 Light 1.27 seconds to travel from Earth to the moon

                 Distance is 380,000 km to the moon

Step:1

                Formula to calculate the speed,

                                [tex]Speed, s=\frac{d}{t}[/tex]................................(1)

               Where, d - Distance

                             t - Time taken

               From given,

                           d = 380000 km

                            t = 1.27 seconds

               Equation (1) becomes,

                                         [tex]s = \frac{380000}{1.27}[/tex]  

                                            = 299212.5984

               Speed of light, s = 299212.5984 kilometers per second

Result:

             The speed of light is 299212.5984 [tex]\frac{km}{s}[/tex] (kilometers per second), if the  light 1.27 seconds to travel from Earth to the moon. If the distance is  380,000 km to the moon.
