Answer:
The pool is filling at the rate of 18 liters per minute.
Step-by-step explanation:
We have been given time in minutes and Volume in liters. We can find the speed at which the volume changes by finding the slope.
Formula for slope will be :
[tex]\frac{v2-v1}{t2-t1}[/tex]
Choosing any 2 values from table. (7,94) and (12,4) denoted as (t1, v1) and (t2, v2)
Calculating the slope we get,
[tex]\frac{4-94}{12-7}[/tex]
= [tex]\frac{-90}{5}=-18[/tex]
This means the pool is filling at the rate of 18 liters per minute.
