Given:
Distance of sun, d=93,000000 miles
Speed of light, s=186000 m/s
The objective is to find the time t taken by the light to reach earth.
It is known that the formula of distance is,
[tex]\begin{gathered} \text{Distance}=\text{Speed}\times Time \\ d=s\times t \\ t=\frac{d}{s} \\ t=\frac{93000000}{186000} \\ t=500\text{ s} \end{gathered}[/tex]To convert into minutes
[tex]\begin{gathered} 1\text{ min=60 s} \\ 500s=8.3\text{ mins} \end{gathered}[/tex]Hence light takes 8.333 mins to reach earth from the sun.
