l (wavelength)

V=fl l=341/496=0.6875m

min loudness (out of phase) L/2=0.3438m

using triangles,

b^2=x^2+2.07^2

(let x be the distance hillary walked and b the distance from the farther speaker to Hillary's present position facing the close speaker)

we now derive another equation to be able to solve

we know that delta d we just solved for is the difference in position of the speakers with reference to Hillary.

b-x= 0.3438......(2)

b^2-x^2=4.285....(1)

solving simultaneously, b=6.404m

x=6.060m
