Question

За 30с часы с боем отбивают 6 раз.За сколько секунд часы пробьют 12 раз?Задача легкая я знаю но в ответах ответ 66 секунд а не 60.Кто-то знает почему????

Answer 1

30 с. - 6 раз.            x=30*12/6=60 с.
x с. - 12 раз

Answer 2

Problem Analysis

The problem states that a clock strikes 6 times in 30 seconds. We need to determine how long it will take for the clock to strike 12 times.

Solution

To solve this problem, we can use the concept of proportions. We know that the clock strikes 6 times in 30 seconds. Let's set up a proportion to find the time it takes for the clock to strike 12 times.

Let x represent the time it takes for the clock to strike 12 times. The proportion can be set up as follows:

6 strikes / 30 seconds = 12 strikes / x seconds

To solve for x, we can cross-multiply and solve for x:

6 * x = 30 * 12

Simplifying the equation:

6x = 360

Dividing both sides by 6:

x = 60

Therefore, it will take the clock 60 seconds to strike 12 times.

Conclusion

The correct answer is 60 seconds, not 66 seconds. It seems there may have been a mistake in the answer you encountered. The correct solution is obtained by setting up a proportion and solving for x, which gives us a result of 60 seconds.
