Answer:

$\dfrac{1}{6}\ \text{cups per hour}$

Step-by-step explanation:

V = volume

r = rate

t = time

Use formula $V=r\cdot t$ connecting volume, rate and time.

In your case,

$V=\dfrac{1}{4}$ cup of water

$t=1\dfrac{1}{2}$ hours

r is unknown.

Substitute all data into the formula:

$\dfrac{1}{4}=r\cdot 1\dfrac{1}{2}\\ \\\dfrac{1}{4}=r\cdot \dfrac{3}{2}\\ \\2\cdot \dfrac{1}{4}=3r\ [\text{Multipled by 2}]\\ \\3r=\dfrac{1}{2}\\ \\r=\dfrac{\frac{1}{2}}{3}\ [\text{Divided by 3}]\\ \\r=\dfrac{1}{6}\ \text{cups per hour}$

Answer:

The average population growth per year is 102.

Step-by-step explanation:

From the given data, we can find the slope which will give us the average rate of change. Our points are:

$(2003, 903)\quad and \quad (2007, 1311)$

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}=\frac{1311-903}{2007-2003}\\\\m=102$

Best Regards!
