You can put this solution on YOUR website!
Let x=amount of time it takes 2 people to finish the same job
\n" ); document.write( "3 people work at the rate of 1/8 of the job per day
\n" ); document.write( "1 person works at the rate of (1/8)/3=1/24 of the job per day
\n" ); document.write( "2 people work at the rate of 2(1/24)=1/12 of the job per day
\n" ); document.write( "So our equation to solve is:
\n" ); document.write( "(1/12)x=1---(1 job that is)
\n" ); document.write( "x=12 days
\n" ); document.write( "ANOTHER WAY
\n" ); document.write( "It takes 3*8=24 people-days to do the job
\n" ); document.write( "3 people can do the job in 24/3=8 days
\n" ); document.write( "2 people can do the job in 24/2=12 days
\n" ); document.write( "etc.
