Let they both complete the job in X hrs
\n" ); document.write( "Jeremy can do the work twice as fast as Brook,
\n" ); document.write( "So time taken by Jeremy will be HALF than that of Brook
\n" ); document.write( "Time taken by Brook = 4hrs
\n" ); document.write( "So Work rate of Brook = 1/4\r
\n" ); document.write( "\n" ); document.write( "Time taken by Jeremy = 2 hrs
\n" ); document.write( "So Work rate of Jeremy = 1/2\r
\n" ); document.write( "\n" ); document.write( " $\"1%2F4%2B1%2F2=1%2FX\"$
\n" ); document.write( " $\"3%2F4=1%2FX\"$ \r
\n" ); document.write( "\n" ); document.write( "So X = 4/3 Hrs,i.e. 1 Hour & 20 Minutes\r
\n" ); document.write( "\n" ); document.write( "So when the work together, they complete the job in 1 Hour & 20 Minutes \n" ); document.write( "

\n" );
