Lorico [155]

Answer:

9.

Step-by-step explanation:

We have been given that dimensions of original photo are 4 inches by 6 inches. We want the photo on the poster to be of dimensions 3 feet by 4 1/2 feet.            

First of all we will convert dimensions of poster from feet to inches.

3\text{ feet}=3\times 12 \text{ inches}=36\text{ inches}

4\frac{1}{2}\text{ feet}=4.5\times 12 \text{ inches}=54\text{ inches}

Now let us compare sides of our original photo with corresponding sides of poster.

\frac{36}{4} =9          

Now let us compare the second pair of corresponding sides.

\frac{54}{6} =9

We have seen that sides of poster are 9 times the sides of our original photo, therefore, the scale factor of this dilation is 9.

av =  \frac{v_{2} - v_{1}}{t_{2} - t_{1}}

t_{1} =  \frac{d}{v_{1}} =  \frac{240}{60} = 4 \: hours  \\ t_{2} =  \frac{d}{v_{2}}  =  \frac{240}{40}  = 6 \: hours

av =  \frac{v_{2} - v_{1}}{t_{2} - t_{1}}  =  \frac{40 - 60}{6 - 4}   =  \frac{ - 20}{2}  =  - 10
