The lower frequency limit for human hearing is usually considered to be 20.0 Hz. What is the corresponding wavelength for this frequency if the air temperature is 20.0 degrees C?
Please help I don't know how to even set up this problem

At 20 degrees C, the speed of sound is 343 m/s. You set up the problem by putting 343 m/s = frequency * wavelength, so...
343 = 20* wavelength
343/20 = wavelength
wavelength = 17.15 m

Look up the speed of sound at this temperature.
The wavelength will be the speed of sound divided by 20 Hz.

frequency X wavelength = Constant = Speed of sound
So get your rear end and find the wavelength do not be lazy. good luck!

speed = frequecy X wavelength
Take the speed of sound 330 m/sec and put it into the formula.
330=20 X
X= 16.5m
Do check your book for the speed of sound at 20 degreesC
