One pump can fill a tank twice as fast as a second pump. If the pumps are used together, they fill the tank in 16 minutes. How long would it take each pump working alone to fill the tank?
\n" ); document.write( "-------------------------
\n" ); document.write( "Faster pipe DATA:
\n" ); document.write( "time = x min/job ; rate = 1/x job/min
\n" ); document.write( "------------------------
\n" ); document.write( "Slower pipe DATA:
\n" ); document.write( "time = 2x min/job ; rate = 1/(2x) job/min
\n" ); document.write( "-----------------------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "time = 16 min/job ; rate = 1/16 job/min
\n" ); document.write( "--------------------------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/x + 1/(2x) = 1/16
\n" ); document.write( "Multiply thru by 16x to get:
\n" ); document.write( "16 + 8 = x
\n" ); document.write( "x = 24 minutes (time for the faster pipe to do the job)
\n" ); document.write( "2x = 48 minutes (time for the slower pipe to do the job)
\n" ); document.write( "==============================================================
