Question

The speed of light is ×2.998108/ms . How long does it take light to travel 10.Cm ? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols.

Answer 1

we are given

speed of light is

$c=2.998*10^8m/s$

we are given

distance =10cm

Firstly, we will change it into m

1m =100cm

so,

distance =0.1m

so,

$d=0.1m$

now, we can use formula

$t=\frac{d}{c}$

now, we can plug values

and we get

$t=\frac{0.1}{2.998*10^8}seconds$..............Answer
