find the angle between hour hand and minute hand when time is 12:40?

• 12 hrs=360 degree
  for hour hand 1hr=30degree -->60min=30 degree -->40min=20 degree
  for minute hand 60min =360 degree -->40min=240 degree
  angle between hour hand and minute hand =240-20=220 degree
  or 360-220=140

• just the simple solution.
  when min hand is on 40 the angle is subtended =240
  and we know that hour hand move 1/2 degree per min so in 40 min it moved 40/2 =20 degree so angle would be 240-20=220 so its reflex angle would be 360-220=140
  there is no need of formula

• ans is:220
  as the hour hand is in h=12
  and minute hand is in m=40
  apply the formulae= (11/2)m-30h
  then it gives 140 but for reflex(ans is negative)
  it is 360-140=220
  don`t worry about the m>h or h>m it will either give ans

• formula:
  angle= 30*Hours-(11/2)*Minutes
  so 30*12-(11/2)*40=360-220=140 ans

• clock is 360 degree circle
  angle cover by hour hand in (12 hrs 40 min) =38/3 is (360/12)*(38/3)= 380
  angle cover by minute hand in 40 min is (360/60)*40=240
  so angle between hh and mh is (380 - 240) = 140

• 12 hrs=360 degree
  for hour hand 1hr=30degree -->60min=30 degree -->40min=20 degree
  for minute hand 60min =360 degree -->40min=240 degree
  angle between hour hand and minute hand =240-20=220 degree

• Angle traced by hour hand in 12 hours is 360 degree
  So, angle traced hour hand in 40 min is (40/60*360/12)= 20 degree
  
  Angle traced by minute hand in 60 min is 360 degree
  so, angle traced by minute hand in 40 min is (40*360/60)= 240 degree
  
  Angle between the hour and minute hand is 240 - 20 = 220 degree

• it will be 220..coz for hr hand angle=20 deg n for min hand angle = 240...

• 140
  formula is modulus(11m/2-30h)
  where m in minutes
  h is hours
  modulus(11*40/2 - 30 * 12)
  modulus(-140)
  140

• Direct fOrmila to find out the ANGLE BETWEEN Hands of a clock is
  M(11/2)-30H= Angle between hands.
  (11/2)*40-30*12=140

• simple formula------
  hours*30-min*12/11
  12*30-40*12/11=316.4

• hour hadle can make 1 degree for every 12 degrees of minute handle.
  time at 12:40 , minute handle make 240 degrees,at that time hours handle can do 17.5 degrees.so 240-17.5=222.5

• total =360 degree minute hand=80 degree therefore diff=280 drgrees
• 13 years agoHelpfull: Yes(0) No(3)
• 60mins=360degree
  now 1mins=360/60=6degree
  in each 12mins the hour handle moves 6degree
  becoz the diffrence b/w 12 to 1 is 5 dots & hour handle takes time to move each 5dots 60mins.hour handle moves 1dot in 60/5=12mins passing by the mins handle.
  so to cover 40 mins the hour handle moves 3dots(40/12=3 & some remainder)so the remaining two mins=2/12=0.17mins.i.e 0.17*6=1.02degree.
  so actual angle=240-(3*6+1.02)=220.98degree.

• from 12 to 12:40 minute hand moves 240 deg(180+60) deg [if hour hand stayed at 12th chamber], cause each division has 30 deg
  by the time minute hand reaches 8th chamber hour hand moves towards 1st chamber 20 deg
  
  cause
  at 12:30 it moves (30deg/2) =15 deg in 30 minutes
  at 12:40 it moves (40deg/2) =20 deg in 40 minutes
  at 1 o clock it moves (60deg/2)=30 deg in 60 minutes----> that is the 30 deg movement from 12th to 1st chamber of the hour hand ,,,,
  
  
  So, we had 240 deg,,
  
  now [240-20]=220 deg
  ans is 220 deg or 140 deg ...

• formula:
  h*30-m*11/2
  h=12,m=40
  12*30-40*11/2
  360-20*11
  360-220
  140

• 12:40
  Consider 12 as 12 and 40 as 8 (8*5=40)
  Now
  1). 12-8 = 4 => 4* 30º = 120º
  2). 40º/2 = 20º => Now add both angles i.e., 120º + 20º = 140º (Which is of CCW)
  3) In CW then 360º - 140º = 220º.
