The distance from the Sun to Earth is

1.50 X 1011 m.

How long does it take for light to cover this distance?

 speed of light= c=dt t=dcspeed\ of\ light=\ c=\frac{d}{t}\rightarrow\ t=\frac{d}{c}  

18

Given:
c= 3x108
d= 1.5x1011
Unknown: t=?
 Equation:t=dcEquation:t=\frac{d}{c}  


 t=1.5×10113×108t=\frac{1.5\times10^{11}}{3\times10^8}
