John can complete a paper route in 20 minutes. Steve can complete the same route in 30 minutes. How long will it take to complete the route if they worked together?
\n" ); document.write( "----------------
\n" ); document.write( "John DATA:
\n" ); document.write( "Time = 20 min/job ; Rate = 1/20 job/min
\n" ); document.write( "---------------
\n" ); document.write( "Steve DATA:
\n" ); document.write( "Time = 30 min/job ; Rate = 1/30 job/min
\n" ); document.write( "----------------
\n" ); document.write( "Together DATA:
\n" ); document.write( "Time = x min/job ; Rate = 1/x job/min
\n" ); document.write( "-----------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "rate + rate = together rate
\n" ); document.write( "1/20 + 1/30 = 1/x
\n" ); document.write( "(30+20)/600 = 1/x
\n" ); document.write( "50/600
\n" ); document.write( "5/60 = 1/x
\n" ); document.write( "x = 60/5 = 12 minutes (time for this to do the job together)
