The "raw" answer is 1800rpm.
Volts is irrelevant.
The "simple" formula for sync speed in rpm is: (60 x frequency)/(Poles/2)
so
(60x60)/(4/2)
3600/2
1800rpm
Its a bear factoring it all out.

From my school days, many years ago, I always remember this type of equation by simple abbreviations, as follow (Note: The last part of the equation is always the portion left out of the rest of the equation):
RIF: RPM = 120 X Frequency / Number of Ploes
PIF: Poles = 120 X Frequency / RPM
FPR: Frequency = Poles X RPM / 120
Works for me.
