Relevant Formulae:

f= 1/T

v= f * wavelength

Solution:

I am not really sure if I am doing this right... but I said since the cup has a diameter of 8cm, the wavelength of the coffee is also 8cm (not sure it this is true)...

If the above is true, all i would need to do is find the frequency. Though I am kind of confused when it says that I am walking at a pace of 1 step per second. How can a frequency be found from this?

After finding these two quanities, and multiplying, a velocity could be found...
