An opamp that is powered from a $\pm\; 5V$ supply is used to build a non-inverting amplifier having a gain of $15$. The slew rate of the opamp is $0.5 \times 10^6 \;V/s.$ For a sinusoidal input with ampitude of $0.3V,$ the maximum frequency (in $\text{kHz}$) up to which it can be operated without any distortion is (up to one decimal place) _______.
