$T = \frac{450}{D}$ $T=450/D$

Explanation:

$we are given T \propto \frac{1}{D}$ $"we are given "Tprop1/D$

$to convert to an equation multiply by k the constant$ $"to convert to an equation multiply by k the constant"$
$of variation$ $"of variation"$

$T = k \times \frac{1}{D} = \frac{k}{D}$ $T=kxx1/D=k/D$

$to find k use the given condition$ $"to find k use the given condition"$

$D = 10, T = 45$ $D=10,T=45$

$T = \frac{k}{D} \Rightarrow k = T D = 10 \times 45 = 450$ $T=k/DrArrk=TD=10xx45=450$

$" the equation is "color(red)(bar(ul(|color(white)(2/2)color(black)(T=450/D)color(white)(2/2)|)))$
