The pendulum of the wall clock makes 198 oscillations in 3.3 minutes, how many oscillations does

The pendulum of the wall clock makes 198 oscillations in 3.3 minutes, how many oscillations does the pendulum make in 12 minutes.

It is known from the condition that the pendulum of the wall clock makes 198 oscillations in 3.3 minutes. We need to find how many oscillations the pendulum makes in 12 minutes.

To solve the problem, we will compose and solve the proportion.

We start by introducing the variable x, denoting for it the number of oscillations in 12 minutes of time.

Now we have enough data to compose and solve the proportion.

So, we get the proportion:

198 hesitation – 3.3 minutes;

x hesitation – 12 minutes.

198 / x = 3.3 / 12;

x = (198 * 12) /3.3 = 720 oscillations.
