One copy machine copies twice as fast as another.
\n" ); document.write( " If both copiers work together, they can finish a particular job in two hours.
\n" ); document.write( " How long would it take the slower copier to complete the job working alone?
\n" ); document.write( ":
\n" ); document.write( "Let t = time for the slower machine to do the job
\n" ); document.write( "then
\n" ); document.write( ".5t = time required by the faster machine
\n" ); document.write( ":
\n" ); document.write( "Let the completed job = 1
\n" ); document.write( ":
\n" ); document.write( "A typical shared work equation
\n" ); document.write( "\"2%2F%28.5t%29\" + \"2%2Ft\" = 1
\n" ); document.write( "multiply thru by .5t, results:
\n" ); document.write( "2 + .5(2) = .5t
\n" ); document.write( "3 = .5t
\n" ); document.write( "t = 6 hrs the slow one alone
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if that is true
\n" ); document.write( "\"2%2F3\" + \"2%2F6\" = 1\r
\n" ); document.write( "\n" ); document.write( "
