Answer:
G
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 )
[tex]\frac{3}{27}[/tex] = k, that is
k = [tex]\frac{1}{9}[/tex]
s = [tex]\frac{1}{9}[/tex] t ← equation of variation
When t = 63, then
s = [tex]\frac{1}{9}[/tex] × 63 = 7 → G
