You can put this solution on YOUR website!
What distance are you using from NYC to LA?
\n" ); document.write( "I'll use 2800 and you can adjust if you need.
\n" ); document.write( "Rate*Time=Distance
\n" ); document.write( " $\"85%2AT=D%5B1%5D\"$
\n" ); document.write( " $\"105%2AT=D%5B2%5D\"$
\n" ); document.write( " $\"D%5B1%5D%2BD%5B2%5D=2800\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"85T%2B105T=2800\"$
\n" ); document.write( " $\"185T=2800\"$
\n" ); document.write( " $\"T=15.13\"$ hrs
\n" ); document.write( "So then in 15.13 hrs, the train from NY has traveled,
\n" ); document.write( " $\"105%2A15.13=1589\"$ miles
\n" ); document.write( "So they meet 1589 miles from NYC or 1211 (2800-1589) miles from LA.
\n" ); document.write( " \n" ); document.write( "

\n" );
