Wave question physics watch

1. I don't know how to do it. It's a simple question but I have no idea I wasn't in for the lesson can someone help me?

- a water wave has a wavelength of 2m. If you see 1 wave every second, what speed must they be travelling at?
2. Use the formula velocity=frequency×wavelength

Frequency is how many waves in a second(in this case it is 1)
Wavelength is given as 2

So multiplying both of them gives 2m/s

Thats all I can get from this.

By the way how old are you?
