1. The problem statement, all variables and given/known data A torpedo fired from a submerged submarine is propelled through the water with a speed of 20.00 m/s and explodes upon impact with a target 2000.0 m away. If the sound of the impact is heard 101.4 s after the torpedo was fired, what is the speed of sound in water? (torpedo is held at a constant speed by propeller) 2. Relevant equations speed=d/t 3. The attempt at a solution I started by reading through the question and thought, if the torpedo travels 20 m/s, and it went 2000 m, then it would be traveling the length in 100 seconds. From there i thought that since it takes 101.4 s for the sound to reach the listener, I could divide 100 by 101.4, concluding that the speed of sound was 1.014 m/s. I think i am completely wrong in how to solve this problem. Please help!
