Person A and person B are standing 95.00 m apart. Person A is on the left and person B is on the right. In between them at a distance of 58.00 m from Person A stands Person C. Persons A and B talk at the same moment. The sound from person A travels through air to person C, while the sound from person B through a very long solid pipe to person C. The sound from person B arrives at person C 0.1518 s before the sound from person A. Calculate the speed of sound in the pipe.
since time = distance/speed, if the speed in air is a, and the speed in pipe is p, we have
58/a = 37/p + 0.1518
By itself, this does not allow us to determine the two speeds.
Now, if you know the speed of sound in air, you can plug that in for a, and determine p.
