Asked by Marie
The Office Jet printer can copy Janet's dissertation in 10 min. The Laser Jet printer can copy the same documents in 8 min. If the two machines work together, how long would they take to copy the dissertation?
10*8=80
80/18= 4.4
so it would take 4 min. is this correct?

4 min won't do it. It will take 4.4 as your original calculation shows.
