R\alpha  \frac{p}{st}
r=k\frac{p}{st}
18=12\frac{k}{1/6*2}
18=12*3k
k=\frac{1}{2}

R α p/(st)

r =  kp/(st)

Where k = constant of proportionality

r = 18, p = 12, t = 2 , s = 1/6

r =  kp/(st)

18 =  k*12/((1/6)*2)

18 = 12k /(1/3)

18 = 12*3*k

18 = 36k

18/36 = k

1/2 = k

k = 1/2

Constant of variation = 1/2 = 0.5
