Question

An accurate clock shows 12 o' clock in the noon. Through how many degree will the hour hand rotate when the clock shows 5 o' clock on the same evening

Answer 1

Answer:150°

Step-by-step explanation:

Total revolution=360°

Hours=12

Angle b/w the numbers=360/12

=30°

So from 12 to 5 , the hour hand goes through 150° , that is 5 numbers.

Hope it helps you

Answer 2

Step-by-step explanation:

Given: The hour hand rotates from 12'0 clock to 5'0 clock

To find: Angle of hour hand rotation.

For calculation of angle between the numbers,

We know that total revolution $= 360$°

∴ angle $= \frac{total revolution}{total hours}$

⇒ $\frac{360}{12}$

⇒ $30$°

For calculation of the degree of rotation,

⇒ $180$°$-130$°

⇒ $150$°

The hour hand rotates $150$° from 12'0 clock in the noon to 5'0 clock.
