Jim can fill a pool carrying buckets of water in 30 minutes. Sue can do the same job in 45 minutes. Tony can do the same job in 1 1/2 hours. How quickly can all three fill the pool?
\n" ); document.write( "------
\n" ); document.write( "Jim rate: 1/(1/2) = 2 jobs/hr
\n" ); document.write( "---
\n" ); document.write( "Sue rate: (1/(3/4)) = (4/3) jobs/hr
\n" ); document.write( "---
\n" ); document.write( "Tony rate = 1/(3/2) = 2/3 job/hr
\n" ); document.write( "-------------------------------------
\n" ); document.write( "Together rate: 1/x jobs/hr
\n" ); document.write( "----------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "rate + rate + rate = together rate
\n" ); document.write( "2 + 4/3 + 2/3 = 1/x
\n" ); document.write( "----
\n" ); document.write( "Multiply thru by 3x to get:
\n" ); document.write( "6x + 4x + 2x = 3
\n" ); document.write( "12x = 3
\n" ); document.write( "x = 1/4 hr.
