What is the smaller angle between both hands at 12:40 am?
Answer & explanation
Correct answer: option 3
In this Question, we will be using the formula:
Angle = ( 60 H - 11 M ) ÷ 2 ,
Where H = Hours, M = Minutes
= ( 60 × 12 - 11 × 40 ) ÷ 2
= ( 720 - 440 ) ÷ 2
= 280 ÷ 2 =140 °
So, smaller angle = 140°
