Algebra, STD2 EQ-Bank 4 MC \(d\) varies directly with \(h\) and it is known that \(d=1.2\) when \(h=5\). The value of \(h\) when \(d=48\) is \(11.52\) \(57.6\) \(200\) \(240\) Show Answers Only \(C\) Show Worked Solution \(d \propto h \ \ \Rightarrow \ \ d=k \times h\) \(\text{Find \(k\) given \(\ d=1.2\) when \(\ h=5\):}\) \(1.2\) \(=5 \times k\) \(k\) \(=\dfrac{1.2}{5}=0.24\) \(\text{Find} \ h \ \text{when} \ \ d=48:\) \(48\) \(=0.24 \times h\) \(h\) \(=\dfrac{48}{0.24}=200\) \(\Rightarrow C\)
