What is the larger angle between both hands at 6:40 am?
Answer & explanation
Correct answer: option 4
In this Question, we will be using formula:
Angle = ( 60 H - 11 M ) ÷ 2 , Where H = Hours, M = Minutes
= ( 60 × 6 - 11 × 40 ) ÷ 2
= ( 360 - 440 ) ÷ 2
= - 80 ÷ 2
= - 40°
So, Smaller angle = 40°
Larger angle = 360 - 40 = 320°
