Question

Given: r is inversely proportional to s. If r = 16 when s = 3, then write the formula for the relation between r and s.

Answer 1

Answer:

B

Step-by-step explanation:

Given that r is inversely proportional to s then the equation relating them is

r = $\frac{k}{s}$ ← k is the constant of proportion

To find k use the condition r = 16 when s = 3

k = rs = 16 × 3 = 48

r = $\frac{48}{s}$ ← equation of variation → B
