Olympic swimmers can swim at a speed of 1.7m/s. If an Olympic swimmer were swimming in the ocean on a day when the wave length of the waves was 20m and the frequency was 1 Hz, would the swimmer be able to swim fast enough to avoid being lifted by the wave? Show your calculations.

Um...yea...I'm a little bamboozled about where to start.

I know that the wave length means the distance between crests, and that the frequency is a little slower than the speed of the swimmer, but that is the extent of my understanding...

Thank you in advance for your help!
