Finding temperature using sound waves

  1. Nov 25, 2008 #1
    hey
    i need to know how to find the temperature of a room using the speed of the sound waves.
    if two rocks are hit together and then each strike is in time with the echo (rocks are 100m away from wall), and the time to make 150 strikes is 92 seconds, what is the air temperature?
    thanks

    You are required to show your own work before we can offer tutorial help.

    What are the relevant equations? What resource can you use to find what the propagation velocity of sound is versus temperature and density?
