The correct answer to the question is 8.33 minutes.
CALCULATION:
The distance of earth from sun s = 150 million km.
We know one million = 10 lakh = [tex]10^6[/tex]
Also 1 km = [tex]10^3\ m[/tex]
Hence, the distance s = [tex]150\times 10^6\times 10^3\ m[/tex]
= [tex]15\times 10^{10}\ m[/tex]
The speed of light c = 300,000 km per second
= [tex]3\times 10^8\ m/s[/tex]
We are asked to calculate the time.
The time of the reaching earth is calculated as -
[tex]time=\ \frac{distance}{velocity}[/tex]
[tex]t=\ \frac{s}{c}[/tex]
[tex]=\ \frac{15\times 10^{10}} {3\times 10^8}\ second[/tex]
[tex]=\ 500\ seconds[/tex]
We know one minute = 60 second.
Hence, 500 seconds = [tex]\frac{500}{60}\ minute[/tex]
= [tex]8.33\ minute[/tex] [ans]
