Explanation:
We first find the distance traveled by the sound, which is given by the equation:
#v# is the velocity of substance
#t# is the time taken
And so, we get:
Here is where you need to be careful, as most questions about sound traveled do this trick. You now have to divide the distance found by
So, the reflecting object is
