The distance of the moon to the Earth is 384,400 km. The speed of light is 2.998 x 108 m/s.
Work out how long it will take light to travel from the moon to the Earth.
Include suitable units.

1.3 seconds

Step-by-step explanation:

Given: Distance of the moon to the Earth = 384,400 km = 384400 x 1000 meters = 384400000 meters.  [1 km = 1000 m]

Speed of light =  m/s = 299800000 m/s

Formula:

Let t be the time taken by the light to travel from the moon to the Earth.

Hence, it will take approximately 1.3 seconds for the light to travel from the moon to the Earth.
