If you have 2 space ships, each traveling at 1/2 the speed of light towards each other, wouldn't they be closing the gap at the speed of light.

solve for x.

Keep in mind that I fail to "grasp" this even after several attempts.
I know I have "move" things like a scale.
-
But I never know WHAT or in WHAT way!
-
Should I subtract 2 from both sides?
multiply 3 on both sides?
add 4?
subtract 8?
add 8?

I am having SERIOUS trouble "getting" this.
Please help me UNDERSTAND this so I can look back and laugh at how hard this is for me.
-
PLEASE try a different way to explain this, other than the conventional ways that are allways taught, because they have done NO GOOD for ME!
-
If somebody wants to take the time... I will converse through email or Yahoo! IM.
-
PLEASE HELP ME! - I want to pass my GED, but I can't get this.
-
Thank you in advance for your help.
-
If you think you can take a few minutes to explain this to me then leave your IM name, and I will IM you.

Isro is in “Satellite launching business” and now goes in commercialization of the launching business. Isro also offers Satellite launching services to countries, which do not have the launch facility.

Space technology needs constant research and development and should not remain limited only to Satellite building and launching. I have witnessed that the best technocrats produced by our IIT, under “aerospace and propulsion” becomes the part of Nasa because of limited scopes offered by Isro. It is a fault of Indian Government that they allot the huge budget for the defense R & D, which has produced very less so far. It doesn’t mean that DRDO doesn’t need it. But, DOS (Dept. of Space) should equally promote Isro for the new R & D in the advanced space technology. I salute Isro scientists who are managing everything in the limited budget.

Our Indian people do not understand the significance of the best establishment (Isro) we have. It is a fault of DOS for not having tried introducing “India and Space” in the Science subjects of schools. DOS should provide complimentary photographs of our developed space technology to be hanged on the walls of the school. It will certainly create the base curiosity among the growing generation of India. After few years, it will be hard to find any person who is not aware about Isro and its developments.

Nasa is more on “exploration” than satellite launching. Moon, Saturn, Mars, Jupiter and Pluto have already been explored by landing or by taking very close look of them. Hubble is for the deep universe and has reveled extraordinary secrets of the deep universe.

Nasa is “exploration”, where as Isro is a “requirement”. So, cannot be compared with each other. I trust the above article will help my friends who is not aware about the difference between Isro and Nasa.
