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

A loudspeaker at the origin emits sound waves on a day when the speed of sound is 340 m/s. A crest of the wave simultaneously passes listeners at the coordinates (38,0) and (0,31).

What are the lowest two possible frequencies of the sound?

Honestly, I am most clueless on how to do this.

2. Relevant equations

I want to say that if the crest passes over each individual 38 and 31 m at the same, that has something to do with the wavelength[tex]\lambda[/tex].

3. The attempt at a solution

I know that v=[tex]\lambda[/tex]f, But I'm unsure how you would use 38 and 31 m to figure out frequencies that would apply for each of them. Any starting point would be appreciated.
