Asked by Jimmy
The back wall of an auditorium is 29.0 m from the stage. If you are seated in the middle row, how much time elapses between a sound from the stage reaching your ear directly and the same sound reaching your ear after reflecting from the back wall?

0.29 m divided by the speed of sound.
You are 14.5 m from the stage and back wall. The reflected wave from the back must make a round trip of 0.29 m before reaching you.

About 340 m/s in air at room temperature. If you are studying acoustics, you should know it by now.
The subject is physics, not physic. Physic has another meaning.
