We know the following two equations: $$\begin{array}{rl}1\text{ bush}& =8\text{ containers}\\ 5\text{ containers}& =2\text{ zucchinis}.\end{array}$$ To find the value of 48 zucchinis in terms of bushes, we multiply by fractions equal to 1 where the numerator and denominator are in different units, canceling units as we go. Thus, we set up the following equation to find our answer: $48\text{ zucchinis}=48\text{ zucchinis}\times \frac{5\text{ containers}}{2\text{ zucchinis}}\times \frac{1\text{ bush}}{8\text{ containers}}=\boxed{15}\text{ bushes}$.
