<u>ANSWER: </u>
The speed of light is m/s.
<u>SOLUTION:
</u>
Given, Light travels meters a year.
And there are about seconds a year.
We need to find how far does light travel per second.
We know that, for anything, the distance, speed and time relation is given by
Distance traveled = travelling speed x time taken ----- (1)
Here, in our problem distance traveled = meters a year.
Time taken = seconds.
Now, substitute the above values in (1)
Speed =
Speed =
Speed = m/s.
Hence, the speed of light is m/s.
