(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Ocean waves with a wavelength of 120 m are coming in at a rate of 8 per minute. What is their speed?

3. The attempt at a solution

[tex]\lambda = 120[/tex]

They are coming in at a rate of 8 per minute, that is 8 in 60 seconds. So the period is

[tex]T=\frac{8}{60}=0.13[/tex]

Now we find frequency

[tex]f=\frac{1}{T}=\frac{1}{0.13}=7.5[/tex]

[tex]v=f \lambda = 120 \times 7.5=900[/tex]

But this is wrong. It is far larger than the actual answer! What did I do wrong?
