I am in desperate need of help in math. I am a really hard worker, and am in grade nine. I need to finish a booklet too raise my mark, so i can get into the pure classes in highschool. I just cant seem to solve this problem. Can you please help me out, thanks. Question : A jet liner and a propeller driven aircraft leave two cities 3000 km apart at the same time and fly toward each other on a collision course. The flights are non-stop. If the propeller driven plane flies at 200 k /h and the jet at 600 km/h, how far will the get fly before these planes crash? ( we must provide a graph, equation, and show how we got it ) . Thank - you so much, this is greatly appreciated. (: </SPAN>\n" );

Their total distance apart is 3000 km, so\r<BR>\n" );
