    When the observer moves towards a stationary source with velocity 'V1V_1', the apparent frequency of the emitted note is 'F1F_1'. When the observer moves away from the source with velocity 'V1V_1', the apparent frequency is 'F2F_2'. If 'V' is the speed of sound in air and F1/F2=2F_1/F_2 = 2, then V/V1=V/V_1 =
