Answer:

Step-by-step explanation:

Given that s varies directly with t then the equation relating them is

s = kt ← k is the constant of variation

To find k use the condition when t = 27, s = 3 , then

3 = 27k ( divide both sides by 27 )

$\frac{3}{27}$ = k, that is

k = $\frac{1}{9}$

s = $\frac{1}{9}$ t ← equation of variation

When t = 63, then

s = $\frac{1}{9}$ × 63 = 7 → G
