Question

How far does light travel in 3.0 days

Answer 1

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.
