If x and y are inversely related then :

$\bigstar\;\; \boxed{\mathsf{x \propto (1)/(y)}}$

$\bigstar\;\; \boxed{\mathsf{(x_1)/(x_2) = (y_2)/(y_1)}}$

Given : x₁ = 5 and x₂ = 15 and y₁ = 2 and y₂ = y

Substituting the values, We get :

$:\implies \mathsf{(5)/(15) = (y)/(2)}$

$:\implies \mathsf{(1)/(3) = (y)/(2)}$

$:\implies \mathsf{y = (2)/(3)}$

$:\implies$ y = 0.67

Answer : When x = 15
$:\implies$ y = 0.67
