Question

HELP ME,PLEASE) Если часовая стрелка часов поворачивается против часовой стрелки с 2 часов дня до 9 часов утра, на сколько градусов она повернется?

Answer 1

Повернётся она на 70 градусов

Answer 2

Calculation of Clockwise Rotation

To calculate the number of degrees the hour hand rotates clockwise from 2 PM to 9 AM, we need to determine the number of hours between these two times and then convert it into degrees.

The time between 2 PM and 9 AM is a total of 19 hours. To convert this into degrees, we need to know that the hour hand completes a full rotation of 360 degrees in 12 hours. Therefore, in one hour, the hour hand rotates 360 degrees divided by 12, which is 30 degrees.

To find the total rotation in degrees, we multiply the number of hours (19) by the rotation per hour (30 degrees):

Total rotation in degrees = 19 hours * 30 degrees/hour

Now we can calculate the result:

Total rotation in degrees = 570 degrees

Therefore, the hour hand will rotate 570 degrees clockwise from 2 PM to 9 AM.
