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
