light travels 3000000 scs if earth is 150 million km away from sun how many minutes it will take the light to come from sun to earth

Respuesta :

  • Speed of light=3×10^8m/s=3×10^5km/s
  • Distance=150million km=150×10^6km

Now

[tex]\\ \rm\longmapsto Speed=\dfrac{Distance}{Time}[/tex]

[tex]\\ \rm\longmapsto Time=\dfrac{Distance}{Speed}[/tex]

[tex]\\ \rm\longmapsto Time=\dfrac{150\times 10^6}{3\times 10^5}[/tex]

[tex]\\ \rm\longmapsto Time=50\times 10^1[/tex]

[tex]\\ \rm\longmapsto Time=500s[/tex]

[tex]\\ \rm\longmapsto Time=8.33min[/tex]

  • Can be written as 8min 20s.
