The same way as 3 phase induction motor...
if the slip of the rotor is s w.r.t forward rotating flux
i.e. the one which rotates same as rotor so
N=Ns(1-s)
where n is actual speed
Ns is the synchronous speed

Answer / amresh kumar ray
We know that single phase induction motor is not self starting. So rotor remains stationary even after application of supply voltage. But once the motor starts it runs at a speed very close to Synchronous speed.
So speed of single phase induction motor is rated as
n=120f/p
