Answer» Hi jogendra , aapke question ka answer yaha hai........ The sound traveled from the place the person stood, to the cliff and then rebounded back to the person , so the person heard the resound/echo. So the sound traveled twice the distance between him/her and the cliff. Distance between cliff and person = 346 m/sec * 5 seconds / 2 = 865 meters |
