It takes 240 commuter train cars to carry 12,000 people into New York City. How many commuter train cars are needed to carry 4,000 people into New York City

Answer 1

To find out how many commuter train cars are needed to carry 4,000 people into New York City, we need to set up a proportion.

We know that 240 commuter train cars carry 12,000 people. Let's set up the proportion:

240 commuter train cars / 12,000 people = x commuter train cars / 4,000 people

To find x (the number of commuter train cars needed to carry 4,000 people), we can cross multiply:

12,000 * x = 240 * 4,000

12,000x = 960,0000

Now, we can solve for x:

x = 960,000 / 12,000

x ≈ 80

Therefore, 80 commuter train cars are needed to carry 4,000 people into New York City.
