Question

A factory can assemble 150 cars in 3 hours. At this rate, how many cars can be assemble in 8 hours?

Answer 1

Lets find the unit rate.

150/3 = x/1

150/3 = 50

Now that we know that a factory can assemble 50 cars per hour, we can multiply that by 8.

150*8 = 1200

Answer: 1200 cars in 8 hours

A fun fact, the assembly line helped factories make cars much faster! :)

Answer 2

To find this out first we will see how many cars they assemble in 1 hour. Lets do it:-

150 / 3 = 50
50 cars per hr

50 * 8 = 400
400 cars in 8 hrs

CHECK OUR WORK;-

400 / 8 = 50
We were RIGHT!!

So, in 8 hrs the factory can assemble 400 cars.

Hope I helped ya!! xD
