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 e

sweet-ann [11.9K]

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

Now

$\\ \rm\longmapsto Speed=\dfrac{Distance}{Time}$

$\\ \rm\longmapsto Time=\dfrac{Distance}{Speed}$

$\\ \rm\longmapsto Time=\dfrac{150\times 10^6}{3\times 10^5}$

$\\ \rm\longmapsto Time=50\times 10^1$

$\\ \rm\longmapsto Time=500s$

$\\ \rm\longmapsto Time=8.33min$

Can be written as 8min 20s.
