Let the time be x \n" ); document.write( "50(x+2)=60(x) \n" ); document.write( "50x+100=60x \n" ); document.write( "10x=100 \n" ); document.write( "x=10 \n" ); document.write( "10\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hence, it takes 10 hours for it to overtake the frieght tarin. \n" ); document.write( "The tatal distance is 600. [50(10+2)=60(10)], = 600=600 \n" ); document.write( " |
