Question

The reflex angle between the hands of a clock at 10.25 is:

Answer 1

Explanation:

Here Hour = 10 , Minute = 25 and the minute hand is behind the hour hand.

Hence the angle  =  30  ( H  −  M /5  )  +  M/ 2

=  30  (  10  −  25 /5  )  +  25 /2

=  30  (  10  −  5  )  +  12.5  

=  30  ×  5  +  12.5  

= 150  +  12.5

= 162.5 °

But the question is to find out the reflex angle.

Reflex angle = 360 - 162.5 = 197.5°

Hope this will help
