Algebra.Com's Answer #237132 by amykazoo(1)![]() ![]() You can put this solution on YOUR website! If the job load is \"1\", then Sam can finish 1/4 per day, Lisa can finish 1/6 per day, and Tom finish 1/2 per day. So, if they work together, how much work can they finish in one day? It should be 1/4+1/6+1/2=11/12 \n" ); document.write( "To know how many days to finish the job if they work together,We use job load \"1\" to divide 11/12, the answer is 12/11 days(which means 26.18 hrs). \n" ); document.write( " |
