-3 degrees F

Step-by-step explanation:

We are given that the previous night the temperature fell from 0 degree Fahrenheit to

$-13 \frac{1}{5}$

Hence change in termperature is

$-13 \frac{1}{5} =\frac{-66}{5}$

Time taken for this change is given as

$4 \frac{2}{5}=\frac{22}{5}$ }

Average rate of change per hour = temperature change /no of hours

The temperature drop per hour can be represented by

=-13 1/5 Divide 4 2/5

= $\frac{-66}{5}$ divided by $\frac{22}{5}$

=-3 degree Fahrenheit

The temperature drop per hour can be represented as $3^{\circ}~F$ or the temperature change per hour can be represented as $-3^{\circ}~F$

Step-by-step explanation:

We are given the following information in the question:

Change in temperature:

$\text{From }0 ~F \text{ to } -13\displaystyle\frac{1}{5}~F$

This fall in temperature too place in $4\displaystyle\frac{2}{5} \text{ hours}$

Temperature drop per hour =

$\displaystyle\frac{y_2-y_1}{\text{Time taken}}\\\\=\frac{-13\frac{1}{5}-0}{4\frac{2}{5}} = \frac{-13\frac{1}{5}}{4\frac{2}{5}}\\\\= \frac{\frac{-66}{5}}{\frac{22}{5}} = \frac{-66}{5}\times \frac{5}{22}\\\\=\frac{-66}{22} = -3^{\circ}~F$

The temperature change per hour can be represented as $-3^{\circ}~F$
