Question

distance travelled by light in 6 months

Answer 1

light travels 3*10^ 8 m in 1 s
so
6 months = 180 days= 180*24 hrs =180*24*60 mins=180*24*60*60 s
so light travels 3*10^8 *180*24*60*60 m in 6 months

Answer 2

Answer:

The distance traveled by light in 6 months is $\bold{4.6656 \times 10^{15} \mathrm{s}}$

Step-by-step explanation:

We know that speed = $\bold{\frac{d i s t a n c e}{t i m e}}$

Distance = speed x time

We know that speed of light = $3 \times 10^{8} \mathrm{m} / \mathrm{s}$

Here we need time in the form of seconds as the speed of light is in the form of seconds

Convert the given time into seconds as it is in the form of months

Assumption:

Consider all the 6 months =30 days on average

Therefore 6 months = 6 x 30=180 days

Now convert  

180 days in terms of seconds

=180 days x 24 hr x 60 min x 60 sec

= 15552000 seconds

So now we have the values of time and speed

Therefore distance = speed x time

= $3 \times 10^{8} \mathrm{m} / \mathrm{s}$ x 15552000s

= 4.6656 $\bold{\times 10^{15} \mathrm{s}}$
