A runs round in 1 minute.\r
\n" ); document.write( "\n" ); document.write( "If B runs at the same speed as A , they will meet in 30 seconds.\r
\n" ); document.write( "\n" ); document.write( "If they have to meet in 20 seconds B has to run faster.\r
\n" ); document.write( "\n" ); document.write( "A would have covered 1/3 in 20 seconds\r
\n" ); document.write( "\n" ); document.write( "B has to cover 2/3 in 20 seconds for them to meet.\r
\n" ); document.write( "\n" ); document.write( "So, B has to run twice as fast as A ANSWER.
