How far does light travel in 3.0 days
MArishka [77]

Answer:

d=7.77\times 10^{13}\ m

Explanation:

We know that the speed of light is equal to 3\times 10^8\ m/s

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,

d=vt

d=3\times 10^8\times 259200\\\\d=7.77\times 10^{13}\ m

So, the light will travel 7.77\times 10^{13}\ m in 3 days.
