Is my answer correct on this wavelength question? Please help!?

What is the wavelength if the velocity is 15.4mm/s and the frequency is 3.25MHz? The answer in the book is 0.000005mm.

I couldn’t figure out how this answer can be.

My Answer:

0.0154m / ( 3.25M *1/sec * sec)

= 0.004738 micrometer

= 4.7mm

mm is the symbol for milimeter not micrometer

the book is saying 0,0000005 mili not micro meter
