so, 32 - 28 is just 4, thus the difference is 4 minutes then.

if we take 32 to be the 100%, what is 4 off of it in percentage?

[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 32&100\\ 4&p \end{array}\implies \cfrac{32}{4}=\cfrac{100}{p}\implies p=\cfrac{4\cdot 100}{32}[/tex]
