ATR 42-500 single engine cruise speed

Could someone please tell me along with a location of where to find it in the AFM.
Single engine cruise speed - to make sure our new routes don't fall outside of the 60 mins rule!

Performance

3.09 One Engine Inoperative
3.09-20 Inflight Normal Conditions Cruise(table)

This is for 72-500, I think is the same for 42-500.

I see an example of that page in another document - but it is not in my 42-320 / 42-500 or 72-212A FCOM!!

I do not fly the ATR - but we have them in our company. Acc to OM 42 200 KIAS = 200 NM - 72 210 KIAS = 210 NM - all old 200 and 300
