How do you find the time for 1000 Hz sound to travel 3 meters?

Hi,

"Somebody makes a noise with a frequency of 1000Hz. Calculate how long it will take to reach somebody 3m away. What will be the wavelength?"

I can't figure out how it fits into any of the formulas I have!


Thanks! :)

What formulas do you have?

What's the speed of sound?
How are frequency and wavelength related?

 

[donkeycopter]

basically just the universal wave equation. the speed of sound is 340m/s.

Good. That's all you need to solve this problem.
