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

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
