two loudspeakers are 1.00m apart. a person stands 4.00m from one speaker. how far must this person be from the second speaker to detect destructive interference when the speakers emit an 115Hz sound? assume the temperature is 20^0C.​

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained
