A quantity h varies directly with w and inversely with p When w is equal to 4 and p is equal to 6 , h is equal to 2 What is the constant of variation?

Direct variation with w and inverse variation with p means h = kw/p, where k is the constant of variation. Substitute h = 2, w = 4, and p = 6: 2 = 4k/6, so k = 3. The constant of variation is 3, choice C.
