\"t\"= time in minutes for Tom to walk to the center of the road
\n" ); document.write( "\"b\"= time in minutes for Bill to walk to the center of the road
\n" ); document.write( "Counting time in minutes starting at 4:00.
\n" ); document.write( "Tom left home at \"-3t\" (meaning \"3t\" minutes before 4:00)
\n" ); document.write( "Bill left home at \"-3b\" (meaning \"3b\" minutes before 4:00).
\n" ); document.write( "Tom arrived at Bill's at \"-t\" .
\n" ); document.write( "According to the problem that was \"-3b%2B11\" , so \"-t=-3b%2B11\"<-->\"t=3b-11\" .
\n" ); document.write( "Bill arrived at Tom's at \"-b\" .
\n" ); document.write( "According to the problem that was \"-3t%2B15\" , so \"-b=-3t%2B15\"<-->\"b=3t-15\" .
\n" ); document.write( "\"system%28t=3b-11%2Cb=3t-15%29\"--->\"system%28t=3b-11%2Cb=3%283b-11%29-15%29\"--->\"system%28t=3b-11%2Cb=9b-33-15%29\"--->\"system%28t=3b-11%2Cb=9b-48%29\"--->\"system%28t=3b-11%2Cb-9b=-48%29\"}--->\"system%28t=3b-11%2C-8b=-48%29\"--->\"system%28t=3b-11%2Cb=%28-48%29%2F%28-8%29%29\"--->\"system%28t=3b-11%2Cb=6%29%29\"--->\"system%28t=3%2A6-11%2Cb=6%29%29\"--->\"system%28t=7%2Cb=6%29%29\"
\n" ); document.write( "So, Tom left \"3t=3%2A7=21\" minutes before 4:00, at \"60-21=39\" minutes after 3:00, meaning at \"highlight%28%223%3A39%22%29\" , and
\n" ); document.write( "Bill left \"3b=3%2A76=18\" minutes before 4:00, at \"60-18=42\" minutes after 3:00, meaning at \"highlight%28%223%3A42%22%29\" .
