9 miles

Explanation:

Question 45

Step1: Find one - way distance

The scale is 1 inch = 5 miles. The map distance between home and mall is 3.4 inches. So the one - way distance (from home to mall) is $3.4\times5$ miles.
$3.4\times5 = 17$ miles.

Step2: Find round - trip distance

To go to the mall and return home, we need to double the one - way distance. So the total distance is $17\times2$ miles.
$17\times2=34$ miles.

Step1: Use the scale to find the actual distance

The scale is 1 inch = 9 miles. The map distance is $\frac{1}{4}$ inch. So the actual distance is $\frac{1}{4}\times9$ miles.
$\frac{1}{4}\times9=\frac{9}{4} = 2.25$ miles.

Answer:

34 miles (corresponding to the option "34 miles")
