distance=velocity* time
\n" ); document.write( "bus for x hours
\n" ); document.write( "train for x+2 hours
\n" ); document.write( "70(x+2)+50x=740
\n" ); document.write( "70x+140+50x=740
\n" ); document.write( "120x=600
\n" ); document.write( "x=5 hours on bus (250 km)
\n" ); document.write( "x+2=7 hours on train (490 km)\r
