\n" ); document.write( "THE DISTANCES ARE THE SAME THUS:
\n" ); document.write( "100T=120(T-12/60)
\n" ); document.write( "100T=120T-120*.2
\n" ); document.write( "100T=120T-24
\n" ); document.write( "100T-120T=-24
\n" ); document.write( "-20T=-24
\n" ); document.write( "T=-24/-20
\n" ); document.write( "T=1.2 HOURS AFTER TRAIN A LEAVES THE STATION THEY WILL MEET.
\n" ); document.write( "PROOF:
\n" ); document.write( "100*1.2=120(1.2-.2)
\n" ); document.write( "120=120*1
\n" ); document.write( "120=120
