Describe 'y' as the distance traveled while 'x' is the time:
\n" ); document.write( "First Car: $\"y+=+50x+%2B+50\"$
\n" ); document.write( "Secont Car: $\"y+=+80x\"$
\n" ); document.write( "Equation:
\n" ); document.write( " $\"80x+=+50x+%2B+50\"$
\n" ); document.write( " $\"30x+=+50\"$
\n" ); document.write( " $\"x+=+5%2F3\"$
\n" ); document.write( "(5/3)(60) = 100 minutes = 1 hour 40 minutes \n" ); document.write( "

\n" );
