The given information in the question is :

Frequency = 170 Hz

1 Hz = $\frac{1}{s}$

Frequency = 170 $\frac{1}{s}$

Wavelength given = 2 m

Speed is unknown which we need to calculate.

Speed can be calculated by using the formula : Speed = wavelength X frequency

By plugging the value of wavelength and frequency in the above formula we get :

Speed = $(2m)\times (170\frac{1}{s})$

Speed = 340 $\frac{m}{s}$
