One person can do a certain job in ten minutes, and another person can do the same job in fifteen minutes. How many minutes will they take to do the job together?
\n" ); document.write( "One person's rate:: 1/10 job/hr
\n" ); document.write( "Other person's rate:: 1/15 job/hr
\n" ); document.write( "--------------
\n" ); document.write( "Together rate:: 1/x job/hr
\n" ); document.write( "-----------------------
\n" ); document.write( "If x represents how many minutes to do the job together, then how much of the job does the slowest person do?
\n" ); document.write( "----------
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/10 + 1/15 = 1/x
\n" ); document.write( "15x + 10x = 10*15
\n" ); document.write( "-----
\n" ); document.write( "25x = 150
\n" ); document.write( "x = 6 minutes (time to do the job together)
\n" ); document.write( "-------
