OCTA Traffic 1:60 rule?

Hi Everyone,

I have heard Pilot's on the radio seperating themselves from traffic OCTA by asking for bearing and distance information from an navigation aid on this occasion it was an NDB. I was wondering whether they would be using the 1:60 rule to do this (as a back up to TCAS, when there in no radar etc), however I am having trouble working through the example below.

Aircraft A inbound on the 360 bearing TO the station at 60nm.
Aircraft B outbound on the 170 bearing FROM the station at 40nm.

What would be the easiest way to calculate the lateral seperation between aircraft A and B using the 1:60 rule.

Also is this kind of calculation used by many of you in the airlines for the purpose of traffic seperation.

Thanks c152g
