The length of the subway is 850

miles. If. 15 inch represents 45

miles, what is the length of the

subway on the map?

Length is equal to 2.83 in.

Step-by-step explanation:

z = 0.15 inches over 45 miles

y = 850 miles

0.15 over 45 = x over 850

x = 850 times 0.15 over 45 which equals to 2.83 in.

z is map scale

x is subway L on map

y is subway L in real life
