Answer:

The length of the subway on the map is
$2.83\ inches$

Explanation:

we know that

The scale on the map is equal to the length of the subway on the map divided by the length of the subway in the actual

so

Let

z------> the scale on the map

x------> the length of the subway on the map

y------> the length of the subway in the actual

z=(x)/(y)

In this problem we have

z=(0.15)/(45)(inches)/(miles)

$y=850\ miles$

substitute and solve for x

(0.15)/(45)=(x)/(850)

$x=850*(0.15)/(45)=2.83\ inches$
