Homework Help: Bat Problem

  1. Sep 5, 2005 #1
    Hi,

    I'm having troubles finding a solution for a problem. Can anybody help me out ? I have no idea where to start so any informations is greatly appreciated. Here's the problem:

    A bat uses sonar at 50kHz to detect objects. The bat is flying in air at 30 degrees Celcius. Directly in front of the bat is a very rapid change of air temperature at 40m distance where the temperature drops to 8 degrees celcius. If the echo return is 1.34s, determine the distance to the bug.

    Thanks alot,
    - alex
