Answer:

\boxed{\sf \ \ \ m = -\dfrac{tn}{t-s} \ \ \ }

Step-by-step explanation:

Hello,

let s assume that m+n is different from 0

we have this equation and we need to find m as a function of t, s, and n

t=\dfrac{ms}{m+n}

<=>

(m+n)*t=ms\\\\ tm+tn=sm\\ (t-s)m = -tn\\ m = -\dfrac{tn}{t-s}

for t-s different from 0, so t different from s

hope this helps

Charra [1.4K]

In this big ol' word problem, this is just an instance of basic multiplication/division.

If it takes it 1 hour for 3 meters...

12 ÷ 3 = 4.

It would take 4 hours for the water level to change to 12 meters.
