Answer:

speed of light is 3 x 10^{8} meters per second.

Step-by-step explanation:

Given : The speed of light is 3 x 10^{5} kilometers per second.

To find :  What is that in standard form.

Solution : We have given 3 x 10^{5} kilometers per second.

First we convert it in to meter per sec.

We can write  

3 x 10^{5} = 300000 kilometer per second .

We know that 1 km = 1000 meter.

Then 300000000 meter per second

Now,   3 x 10^{8} meter per second.

Therefore,  speed of light is 3 x 10^{8} meters per second.
