Answer:
[tex]d=7.77\times 10^{13}\ m[/tex]
Explanation:
We know that the speed of light is equal to [tex]3\times 10^8\ m/s[/tex]
We need to find how far the light travel in 3 days.
Speed of an object is equal to distance covered divided by time taken.
Also, 1 day = 86400 s
3 days = 259200 s
So,
[tex]d=vt[/tex]
[tex]d=3\times 10^8\times 259200\\\\d=7.77\times 10^{13}\ m[/tex]
So, the light will travel [tex]7.77\times 10^{13}\ m[/tex] in 3 days.
