You watch a distant carpenter driving his nails into the side of a house at a regular rate of 1 stroke per second. You hear the sound of the blows exactly synchronized with the blows you see. You then hear one more blow after you see him stop hammering. How far away is he? Justify your ANSWER---BE BRIEF.
Solution1 : The information tells you that sound travels for one second before reaching you the actual distance will depend on temperature, since the speed of sound varies with temperature, at 20 deg C it is approx 343m/s, so if this is a nice spring day, you are 343m away
