Frequency is simply cycles per second, or Hertz (Hz). Since you dip your finger in the water twice per second, the frequency is 2 Hz.
The velocity of a wave (v) is equal to the length of the wave (l) times the frequency (Hz), or v=lf. Since crest to crest is separated by 0.19 meters, that can be assumed to be the length of the wave. In this case, the velocity of the resulting waves is
v = (0.19 m)*(2 1/sec) = .38 m/sec
