Ocean waves are traveling to the east at 4m/s with a distance of 20m. between crests. With what frequency do the waves hit the front of the boat
a. when the boat is at anchor and
b. when the boat is moving westward at 1m/s?

Remember that
frequency*wavelength = velocity
so
frequency = 4/20 = 1/5 = .2 Hz
If the boat is travelling west at 1 m/s the apparent wave velocity is 5 m/s and so
frequency = 5/20 = 1/4 = .25 Hz.
