The hour hand of a clock moves from 3 to 8 o'clock through how many degrees does it move

Answers

The number of degrees does it move is 150 degrees.

The following things should be considered:

Since there are 12 parts.
Each one should we 30 degrees i.e. $= 360/ 30$
Now 8 - 3 = 5
So, the angle should be $= 5* 30$ = 150 degrees.

Therefore we can conclude that The number of degrees does it move is 150 degrees.
