On the moon you would weigh around 19 pounds!
Velocity of a wave = frequency × wavelength
you are given the velocity(speed) and the wavelength, they want you to solve for the frequency. so you can plug in the values that you are given and solve for the unknown. This is where your algebra skills come in :)
20m/s = f × 0.50
20/0.50 = f
40 Hertz = f or f = 40 Hertz
hope this helps :)
