Answer:

s = 0.3m

Step-by-step explanation:

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

s = km ← k is the constant of variation

To find k use the condition

s = 9 when m = 30

9 = 30k ( divide both sides by 30 )

\frac{9}{30} = k

s = \frac{9}{30} m or

s = 0.3m ← equation of variation
