be the number of hours worker A takes to do the job by himself. Then

is the time it takes worker B, the faster worker.\r

hours, he can do

of the job in one hour. Likewise B can do

of the job in 1 hour. Working together they can do:\r

\n" ); document.write( "\n" ); document.write( "Just solve for

to determine the time for A to do the job by himself and then subtract 3 to get how long it takes B to do it herself. The quadratic equation that you will have to solve does NOT factor, so use the quadratic formula.\r
