Jake can mulch a garden in 30 minutes. together, jake and ross can mulch the same garden in 16 minutes. how much time t, in minu

Gelneren [198K]

"Jake can mulch a garden in 30 minutes." So, for 1 min Jake can mulch 1/30 part of a garden.

Ross can mulch the park for x minutes. So, for 1 min Jake can mulch 1/x part of a garden.

If they work together, for 1 min they will mulch (1/30 + 1/x) part of the garden.

At the same time, we know, that of they work together they can mulch the garden in 16 min, so for 1 min they will mulch 1/16 part of the garden.

Now, we can write an equation

$\frac{1}{30} + \frac{1}{x} = \frac{1}{16} \\ \\ \frac{1}{x} = \frac{1}{16} - \frac{1}{30} \\ \\ \frac{1}{x} =\frac{30-16}{16*30} \\ \\ \frac{1}{x} =\frac{14}{16*30} \\ \\x=\frac{16*30}{14}$

x≈34.3 (min)
