The pressure

(P)

of wind on a sail varies jointly as the area

(A)

of the sail and the square of the velocity

(V)

of the wind. The pressure on a square foot is

1

pound when the velocity is

16

miles per hour. The velocity of the wind when the pressure on a square yard is

36

pounds is:

<span class='latex-bold'>(A)</span>\ 10\frac {2}{3} \text{ mph} \qquad<span class='latex-bold'>(B)</span>\ 96 \text{ mph} \qquad<span class='latex-bold'>(C)</span>\ 32\text{ mph} \qquad<span class='latex-bold'>(D)</span>\ 1\frac {2}{3} \text{ mph} \qquad<span class='latex-bold'>(E)</span>\ 16 \text{ mph}
