Question 1157868
<br>
An alternative solution method....<br>
Working alone, Matt takes twice as long as Pam.  [given]
When they work together, Pam does 2/3 of the job.  [logical reasoning]
So Pam does 2/3 of the job in 8 hours; that means working alone it will take her 8(3/2)=12 hours to do the whole job.<br>
