Question

THE

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?​

Answer 1

The speed of light is 299212.5984
`(km)/(s)` (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.

Step-by-step 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,

`Speed, s=(d)/(t)`................................(1)

Where, d - Distance

t - Time taken

From given,

d = 380000 km

t = 1.27 seconds

Equation (1) becomes,

`s = (380000)/(1.27)`

= 299212.5984

Speed of light, s = 299212.5984 kilometers per second

Result:

The speed of light is 299212.5984
`(km)/(s)` (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.
