Joy is 990m away  from the woman.
.Because speed of air (given) = 330m/s
Time taken by the sound to reach Joy = 3 seconds         
Distance between Joy and the woman (sound source) = Speed * Time                                                                              =     330 * 3       = 990                                       
Therefore ,Distance between Joy and the woman (sound source)=   990 m
