Say they are $\"+d+\"$ miles apart
\n" ); document.write( "Let the time for them to meet = $\"t\"$
\n" ); document.write( "They approach each other at the sum of their speeds
\n" ); document.write( " $\"+d+=+%28+50+%2B+30+%29%2At+\"$
\n" ); document.write( " $\"+t+=+d%2F80+\"$
\n" ); document.write( "For the 50 mi/hr train:
\n" ); document.write( "It's distance is $\"+50%2A%28d%2F80+%29+\"$
\n" ); document.write( "For the 30 mi/hr train:
\n" ); document.write( "It's distance is $\"+30%2A%28+d%2F80+%29+\"$
\n" ); document.write( " $\"+50%2A%28+d%2F80+%29+%2B+30%2A%28+d%2F80+%29+=+d+\"$
\n" ); document.write( " $\"+%285%2F8%29%2Ad+%2B+%283%2F8%29%2Ad+=+d+\"$

\n" ); document.write( "The 50 mi/hr train goes 1/4 of the distance between them further \n" ); document.write( "
