Answer:
The value of s is 0.175.
Explanation:
Given,
r and s vary inversely,
That is,
[tex]r\propto \frac{1}{s}[/tex]
[tex]\implies r=\frac{k}{s}[/tex]
Where, k is the constant of proportionality,
We have, r = 1200 if s = 0.35,
[tex]\implies 1200 = \frac{k}{0.35}[/tex]
[tex]\implies k=1200\times 0.35 = 420[/tex]
Thus, the equation that shows the relation between r and s is,
[tex]r=\frac{420}{s}[/tex]
[tex]\implies s=\frac{420}{r}[/tex]
If r = 2400,
[tex]s=\frac{420}{2400}=0.175[/tex]
