So am I, what was the question ?

and while we are at it what was your attempt at an answer (you did read the homework rules here didn't you) ?

Sorry the post submitted before I finished, this is the question.

An audio speaker producing a steady sound at an outdoor concert is 42 ft away from you. If you move to a position where the speaker is 70 ft distant, by what factor will the amplitude of the sound change?

Do you know inverse square law?

Also, are you aware of the relationship between the amplitude and the intensity of a sound wave? Hint: they are not directly proportional.
