A series DC motor has a resistance of 8 2 between its terminals. The motor runs at 1,393 rpm at 230 V taking a current of 8 A. What will be the speed at which the motor runs when it is connected in series with a 7 resistance, if there is no change in the supply voltage and current. Give your answer to two decimal places.
