The average distance from the sun to Pluto is approximately 6.10 × 109 km. How long does it take light from 
the sun to reach Pluto? Use the speed of light from the previous question to help you.

Sagot :

[tex]V= \frac{S}{t} [/tex]
[tex]t= \frac{S}{V} [/tex]
[tex]t= \frac{S}{c} [/tex]
[tex]t= \frac{6.1*10^{12}}{299792458} [/tex]
[tex]t=20347.4098071s[/tex]

It takes 20347.4098071s for light from the sun to reach Pluto.
The 6.1*10^9 is replaced by 6.1*10^12 on line 4 because we convert the distance from km to m. 
c = speed of light. If a different value was given in the previous question then use that instead of the value I used to do the final calculation.
