A series DC motor has a resistance of 7 Q between its terminals. The motor runs at 1,259 rpm at 230 V taking a current of 12 A. What will be the speed at which the motor runs when it is connected in series with a 4 Q2 resistance, if there is no change in the supply voltage and current. Give your answer to two decimal places.
