Question

What is the degree measure of the acute angle formed by the hands of 12 hour clock that reada exactly 1 o’clock

Answer 1

30°

Explanation:

In a 12 hour clock, at exactly 1 o'clock the large hand and the small hand show 12 and 1 respectively.

So, there is an arc length of 5 minutes between them.

Now, a total of 60 minutes of rotation gives 360° rotation.

Therefore the 5 minutes of rotation will give
`(360 * 5)/(60)= 30` degree.

Therefore, at 1 o'clock the two hands will make a 30° angle. (Answer)
