Question

Can anyone show the process of this maths. Question number 12.

Answer 1

Complete angle is equal 360°
The hand of a clock rotate 360°in one revolution completing 12 hour . There are 60 minutes in one hours .So there 12×60 = 720 minites. So for every one one minute the hand rotate
$\frac{360}{729}$
degrees, equals to 0.5 degrees . So for five minutes it rotates 5 × 0.5 = 2.5 degrees.
hope it helps.

Answer 2

We know that 12 hours makes an angle of 360.

So,

1 hour = 360/12.

            = 30 degrees per hour.

            = 30/60

            = 0.5 degrees per minute.


Now,

Given, 5 minutes = 0.5 * 5

                              = 2.5 degrees.


Therefore the hour hand moves 2.5 degrees.


Hope this helps!
