You can put this solution on YOUR website!
to make things easy, you can think of this as
\n" ); document.write( "one person standing still and the other traveling
\n" ); document.write( "at the sum of their speeds from A to B
\n" ); document.write( "------------------------------------
\n" ); document.write( "Let \"+t+\" = time in hrs until they meet
\n" ); document.write( "\"+100+=+%28+100+%2B+50+%29%2At+\"
\n" ); document.write( "\"+100+=+150t+\"
\n" ); document.write( "\"+t+=+100%2F150+\"
\n" ); document.write( "\"+t+=+2%2F3+\"
\n" ); document.write( "\"+%282%2F3%29%2A60+=+40+\"
\n" ); document.write( "They will meet in 40 min
\n" ); document.write( "-----------------------
\n" ); document.write( "check:
\n" ); document.write( "Lucia's equation:
\n" ); document.write( "\"+d%5B1%5D+=+100t+\"
\n" ); document.write( "\"+d%5B1%5D+=+100%2A%282%2F3%29+\"
\n" ); document.write( "\"+d%5B1%5D+=+200%2F3+\"
\n" ); document.write( "-------------------
\n" ); document.write( "Jack's equation:
\n" ); document.write( "\"+d%5B2%5D+=+50t+\"
\n" ); document.write( "\"+d%5B2%5D+=+50%2A%282%2F3%29+\"
\n" ); document.write( "\"+d%5B2%5D+=+100%2F3+\"
\n" ); document.write( "------------------
\n" ); document.write( "\"+d%5B1%5D+%2B+d%5B2%5D+=+200%2F3+%2B+100%2F3+\"
\n" ); document.write( "\"+d%5B1%5D+%2B+d%5B2%5D+=+300%2F3+\"
\n" ); document.write( "\"+d%5B1%5D+%2B+d%5B2%5D+=+100+\"
\n" ); document.write( "OK\r
\n" ); document.write( "\n" ); document.write( "
