It takes light 1.27 seconds to travel from Earth to the moon. If the distance is
380,000 km to the moon, what is the speed of light?

The speed of light is 299212.5984 (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,

                                ................................(1)

               Where, d - Distance

                             t - Time taken

               From given,

                           d = 380000 km

                            t = 1.27 seconds

               Equation (1) becomes,

                                            = 299212.5984

               Speed of light, s = 299212.5984 kilometers per second

Result:

             The speed of light is 299212.5984 (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.
