gen nav question HELP!

Hi can someone please explain this question to me. I don't really understand how it isn't a track change of zero. Its following the same line of latitude but the longitude is changing. wouldn't this mean that its just following a straight line towards the east?

The following points are entered into an inertial navigation system (INS). WPT 1: 60°N 30°W WPT 2: 60°N 20°W WPT 3: 60°N 10°W The inertial navigation system is connected to the automatic pilot on route (1-2-3). The track change when passing WPT 2 will be approximately:

4° decrease
9° increase
zero
9° decrease

Some help here would be great thanks






Am I right in thinking that I need to find the conversion angle?
I.E. find the convergency and half it? that way I know that for every 5degrees it will decrease by that number?
