1. Find the variation constant and and an equation of variation where y varies directly as x and y y=42 when x=6

variation constant is K=

equation of variation is y=

since y = kx, k= 42/6 = 7

------------------------

1/t = 1/6 + 1/4 = 5/12

so,

t = 12/5

makes sense, since if they each took 6 hours, they could do it together in 3. If the each took 4 hours, they could do it together in 2.
