Any help would be greatly appreciated.

**bobpursley**, Saturday, September 12, 2009 at 4:07pmIn 18*22min, laserjet can do 22, and the officejet can do 18. So the rate is

rate= number/time= (18+22)/22*18=40/396min = 1dissertation/9.9 min

that answers it, but formally

dissertations= rate*time

time= dissertations/rate= 1dissertation/(1dissertation/9.9min)= 9.9 min
