Question

A woman was chopping wood using an axe near a valley. It took Joy 3 seconds to hear the sound from a woman chopping wood. how far is Joy from the woman chopping wood
[speed of sound is 330m/sec]

Answer 1

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
