Question about angular and linear feedrates

I would like to know how most (all) control programs will handle the
feedrate for the following moves:

A-axis is angular with feedrate expressed in degrees/sec
X-axis is linear with feedrate expressed in inches/min

Assume that I am always starting at X0 and A0 for these moves.

If I command: G01 A180 F1.0 it should take 180 seconds to make the move.
If I command: G01 X0.5 F1.0 it should take 30 seconds to make the move.

My question is how long should the following move take starting at A0 X0:

G01 A180 X0.5 F1.0

Does it take 30 seconds or 180 seconds?

Thank youf or your help.
