A stretched rubber band has a length of 0.10m and a fundamental frequency of 440Hz. What is the speed at which waves travel on the rubber band?
I need some ideas to do this problem. Thanks!

A half wavelength is .1 m long
A wavelength is therefore .2 meters long
distance = rate * time
the wave goes a wavelength in a period
The period is one over the frequency. 
You know the wave equation, f*lambda=v
lambda is twice the length of the rubber band.
