Leo fnished 2/3 of a job in 12 hours. When he was joined by Ed, they completed the job in 2 hours. How many hours would it take Ed to do the job alone.
\n" ); document.write( "---------------
\n" ); document.write( "Leo DATA:
\n" ); document.write( "Time = (2/3) job/12 hr = 3/2[(2/3)job/12 hr](2/3)= 2job/36hr=1job/18hr
\n" ); document.write( "Rate = (1/18)job/hr.
\n" ); document.write( "----------
\n" ); document.write( "Together DATA:
\n" ); document.write( "Time = 12 hrs/job ; Rate = (1/12)job/hr
\n" ); document.write( "--------------
\n" ); document.write( "Ed Data:
\n" ); document.write( "Time = x hrs/job ; Rate = (1/x) job/hr
\n" ); document.write( "==============
\n" ); document.write( "EQUATION:
\n" ); document.write( "rate + rate = rate together
\n" ); document.write( "1/18 +1/x = 1/12
\n" ); document.write( "Multiply thru by 36x to get:
\n" ); document.write( "2x + 36 = 3x
\n" ); document.write( "x=36 hrs (Time for Ed to do the job alone.)
