the speed of a transverse wave on a string is 450m/s while the wavelength is 0.18m. The amplitude of the wave is 2.0mm. How much time is required for a particle of the string to move a total distance of 1.0km....

The thing that confuses me about this question is the amplitude of the wave as i do not know how to incorporate it into my calculations. Please help me.

Something has to be wrong. If the amplitude is 2mm, then the max the string particles move is 4mm (up and down). It cannot move 1km.
