Working together, Brad and Mike can complete a job in 3 hours. If it takes mike 5 hours to do the job alone,how long would it take Brad to do the job alone?
\n" ); document.write( "------
\n" ); document.write( "Together rate:: 1/3 job/hr
\n" ); document.write( "----------
\n" ); document.write( "Mike rate: 1/5 job/hr
\n" ); document.write( "----
\n" ); document.write( "Brad rate: 1/x job/hr
\n" ); document.write( "==========================
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/x + 1/5 = 1/3
\n" ); document.write( "----
\n" ); document.write( "15 + 3x = 5x
\n" ); document.write( "2x = 15
\n" ); document.write( "x = 7.5 hrs (time for Brad to do the job alone)
\n" ); document.write( "===============================================
