Question

How far can light travel in 1 year? Remember there are 3.15576 x 10^7 seconds in a single year.

Answer 1

Answer: $9.465\times 10^{15}\ m$

Step-by-step explanation:

Given

Seconds in a year is $3.155\times 10^7$

We know

$Distance=speed\times time$

Speed of light in vacuum is $3\times 10^8\ m/s$

So distance traveled $=3\times 10^8\times 3.155\times 10^7$

$distance=9.465\times 10^{15}\ m$
