Question

A police car moving at 22 m/s chases a motorcyclist. The police man sound his horn at 176 Hz, while both of them move towards a stationary siren of frequency 165 Hz. If the motorcyclist does not observe any beats, the speed of motor cycle is $text (velocity of sound is end text 330 m s to the power of negative 1 end exponent text ) end text$

33 m/s
22 m/s
zero
11 m/s

The correct answer is: 22 m/s
