Knowing that the formula for average velocity is:

v=\frac{x_{2}-x_{1}}{t_{2}-t_{1}}

Being said that, we know that the person's displacement is zero because it returns to its starting point

x_{2}=x_{1}

That means x_{2}-x_{1}=0

v=\frac{0}{t_{2}-t_{1}}=0

A wave has a wavelength of 8 mm and a frequency of 4 hertz. What is its speed?
Valentin [98]

First convert the units to m and then multiply the values to calculate its propagation or wave speed.

C = lambda • frequency.
