You are the only one that can solve this because only you know how many jobs there are and how the machines work.

They'll finish the job exactly as they were supposed to. But since the other machine broke down, they have to make up for time.
My answer: 6:00 a.m.
(if they're all working together...if separate jobs, then : X: none
Y: 6:00 p.m. ; Z: 8:00 p.m.)
If X got fixed, then times change.

*********10:00pm************
machine x has 6 hours worth of work left
machine y will finish 2 hours before machine z
so give machine y 2 hours worth of work
then dived the rest between the two
that would be 2 hours each
if machine z would be finished at 8:00pm
add the extra 2 hours... then you got 10:00pm
