Detailed explanation-1: -The hour hand moves 360 degrees / 12 in an hour = 30 degrees. It follows that in a minute it moves 30 degrees / 60 = 1/2 degree. Therefore in a second it moves 1/2 degrees / 60 = 1/120 degree.
Detailed explanation-2: -In 1 and ½ hours, the minute hand of the clock rotates through an angle of 540°.
Detailed explanation-3: -Angle turned by the hour hand in 1 minute is 12∘
Detailed explanation-4: -Thus, the angle between the clock hand and minute hand at 2o’clock will be 60∘. Note: Always remember that the angle between two consecutive numbers in a clock of 12 hour is always 30∘.
Detailed explanation-5: -Within an clock, there are 60 total minutes. Each minute that passes, the minute hand advances 6 degrees.
