#### Answer

$n=\dfrac{103.68}{s}$ and $n \approx 27$

#### Work Step by Step

General equation for inverse variation is given by $y=\dfrac{k}{x}$ Here, we have $n=\dfrac{k}{s}$ and $54=\dfrac{k}{1.92} \implies k=103.68$ Thus, our formula is: $n=\dfrac{103.68}{s}$ Set $s= 3.87$ $n=\dfrac{103.68}{3.87} \approx 27$
