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.
