Petunia and Petal worked for 5 hours and completed 1(1/24) jobs. if Petal took 12 hours to do 1 job, how long did it take petunia to do 2 jobs?
\n" ); document.write( "----------------
\n" ); document.write( "Working together DATA:
\n" ); document.write( "Time = 5 hrs/[(25/24)job]; Rate= 1/5 [(25/24)job/hr]=(5/24)(j/h)
\n" ); document.write( "--------------
\n" ); document.write( "Petal DATA:
\n" ); document.write( "Time=12 hrs/job ; Rate = (1/12) job/hr.
\n" ); document.write( "------------------
\n" ); document.write( "Petunia 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( "(1/12)(j/h) + (1/x)(j/h) = (5/24)(j/h)
\n" ); document.write( "Multiply thru by 24x to get:
\n" ); document.write( "2x+24=5x
\n" ); document.write( "3x=24
\n" ); document.write( "x=8 hours for Petunia to do one job.
\n" ); document.write( "2x=16 hrs for Petunia to do two jobs.
