One train's speed = x
\n" ); document.write( "Other's trian's speed = 2x
\n" ); document.write( "TIme they meet after = 2 hours.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2(x+2x)=90
\n" ); document.write( "2(3x)=90
\n" ); document.write( "6x=90
\n" ); document.write( "x=15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2(15)=30.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, the speed of one train is 15mph and for other its 30mph.
