Thank you for the opportunity to help you with your question!

First, realize that the television picture is transmitted by electromagnetic waves which travel at the speed of light.

Then, we know the speed of light is 299,792,458 m/s which is 299,792.458 km/s which is about 3x10^5 km/s

So, we divide 2.08x10^8 km by 3x10^5 km/s to get

693.33 second which equals 11.56 minutes

Please let me know if you need any clarification. I'm always happy to answer your questions.
