Find the constant of variation
From the question, the variation is as follows
Convert variation to equation
Where k represents the constant of variation
Make k the subject of formula;
Multiply both sides by s * t
Divide both sides by p
Substitute the values of p, r, s and t in the above equation
Divide numerator and denominator by 6
Hence, the constant of variation is;
The variable in equations are always the letters so the variable in this equation is y
