1. The problem statement, all variables and given/known data A stone is dropped into a well. The splash is heard 3 seconds later. What is the depth of the well? 2. Relevant equations the change in t= change in length/ velocity of sound 3. The attempt at a solution V= 343 m/s which is the speed of sound Ok I solved for depth. I made L=d. Then my equation looked like this. D= t * v D= (3s) * 343 m/s = 1029 meters The answer is 41 meters if you round off. I've seen solutions to this problem, but I need a walkthrough as to how to do it because I don't understand how the experts on cramster solved this problem.
