Yes...

He is right.

if machine B worked 5 hours more,it means that it worked 200 hours more to keep up with machine A. i.e. machine A overtook by 200 hours...

 

Each hour both the machines works, machine A overtakes machine B by 5 hours... To overtake by 200 hours machine A has to work (200/5)= 40 hours
