The first ship has a one-hour head start, and thus has gone 20 already. Then the second ship catches up in:
\n" ); document.write( "20x+20=25x
\n" ); document.write( "5x=20
\n" ); document.write( "x=4
\n" ); document.write( "After five hours , the first ship has traveled 5(20), or 100 miles. The second ship ,after four hours, has traveled 4(25), or 100 miles also!!!!!!!!
\n" ); document.write( "
\n" );
