It takes one worker 5 hrs to do the same job that it takes another worker 3hrs to do.If they work together,how long can the job be done?15/8hrs,8/15hrs,4hrs,or 2hrs?
\n" ); document.write( "-----------
\n" ); document.write( "1st worker DATA;
\n" ); document.write( "Time = 5 hr/job ;Rate = 1/5 job/hr
\n" ); document.write( "--------------
\n" ); document.write( "2nd worker DATA:
\n" ); document.write( "Time = 3 hr/job ; Rate = 1/3 job/hr
\n" ); document.write( "-----------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "Time = x hr/job ; rate = 1/x job/hr
\n" ); document.write( "---------------------
\n" ); document.write( "EQUATION\"
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/5 + 1/3 = 1/x
\n" ); document.write( "Multiply thru by 15x to get:
\n" ); document.write( "3x + 5x = 15
\n" ); document.write( "8x = 15
\n" ); document.write( "x = (15/8) hrs (time to do the job working together)
