Second hint: Set up a proportion: $$\frac{90 \space\text{seconds}}{x \space\text{seconds}} = \frac{30 \space\text{jugs}}{90 \space\text{jugs}}$$ Solve for x, then convert to minutes

4.5

90/30 *90sec=90/30 *1.5min=4.5 min

Time (Sec) : Milk Jugs = Time(Sec) : Milk Jugs 90 : 30 = x : 90 So: $\frac{90}{30} = \frac{x}{90}$ $\frac{x}{90} = 3$ $x = 270\; (Seconds)$ So to convert it into minutes divide it by 60: $270 \; Seconds = \frac{270}{60} \implies \color{blue}{4.5 \; \; minutes.. }$
