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 90 minutes. How quickly can all three fill the pool together? (Answer is 15 minutes - I have no clue how to even start!)\r
\n" ); document.write( "\n" ); document.write( "Let filling the pool be 1 job\r
\n" ); document.write( "\n" ); document.write( "Jim can fill the pool in 30 minutes
\n" ); document.write( "Jim can do 2 jobs in 1 hour\r
\n" ); document.write( "\n" ); document.write( "Sue can fill the pool in 3/4 hour
\n" ); document.write( "She can do 4/3 of the job in 1 hour\r
\n" ); document.write( "\n" ); document.write( "Tony can do the job in 3/2 hours
\n" ); document.write( "he can do 2/3 job in 1 hour\r
\n" ); document.write( "\n" ); document.write( "In 1 hour all 3 together will do 2 +4/3 +2/3 of the job\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "They will do 12/3 of the jobs in 1 hour( they can fill the pool 4 times)\r
\n" ); document.write( "\n" ); document.write( "4 jobs they do in 1 hour\r
\n" ); document.write( "\n" ); document.write( "1 job they do in 1/4 hour or 15 minutes.\r
