Question

Isabella filled her pool with water at a constant rate.

Answer 1

(184-94)/5=18

This means that she fills up 18 liters every minute. Thus she will be done in->

184(original amount)+(2 minutes (time passed during first data point)*18(rate of water)=184+36=220

To find the total time taken we divide 220 by 18 which is 220/18=12 2/9

Answer 2

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 :

$\frac{v2-v1}{t2-t1}$

Choosing any 2 values from table. (7,94) and (12,4) denoted as (t1, v1) and (t2, v2)

Calculating the slope we get,

$\frac{4-94}{12-7}$

= $\frac{-90}{5}=-18$

This means the pool is filling at the rate of 18 liters per minute.
