The lawn order lawnmower factory can produce 12 lawnmowers in 8 hours . how many hours will take the factory to produce 30 lawnmowers?

The correct answer is 20.

Step-by-step explanation:

Well, let's see the facts we have.

We know that the factory can produce 12 lawnmowers in 8 hours.

Now what we need to find out is how many hours it will take the factory to do 30 lawnmowers.

Having 3 data resolved and only one icognite, the most convenient thing would be to do a cross-multiplication.

If 8 hours 12 lawnmowers

Then x hours 30 lawnmowers.

x.12 = 30.8

x.12 = 240

x = 240:12

x = 20

With this information we can say that it will take 20 hours for the factory to do 30 lawnmowers.
