Question

The length of the subway is 850
miles. If .15 inch represents 45
miles, what is the length of the
subway on the map?

Answer 1

Answer:

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
