The angle between the minute hand and the hour hand of a clock when the time is 4.20, is:

A. 0º
B. 10º
C. 5º
D. 20º

• b is ans
  hour hand moves 1degree when min hand moves 2degree

• Ans. A
  bcoz both at same position
• 12 years agoHelpfull: Yes(0) No(2)
• this is simple qustion.
  both hand same line so ans will be A = 0A

• its 5 degree

• at 4.20 hr hand is slightly greater than 4'o clock so ans is 10 deg
  
  mnt hand moves 120deg in 20 mnts
  and hr hand at exact 4 is 120 bt in 4+1/3 hr it is 10 greater than mnt

• ans is b)10 degree
  It is 4 degree.
  Because hour hand moves 30 degree in 1hour.
  4:20 = 4 +20/60 = 4+1/3 = 13/3.
  So it is 1/3 hours passed so it rotates 10 degree.
  Total angle of hours hand is 30*4+10 = 130 degree.
  
  Minute hand moves 6 degree in 1 minute = 20*6 = 120 degree.
  So 130-120 = 10 degree.

• The total angle made by the minute hand during an hour(60 mins) is 360degrees.
  For 40 mins= (40/60)*360=240degrees
  
  The angle between the hour hand the minute hand will therefore, be somewhere between 240 – 90 = 150degrees.
  
  as the hour hand is between 3 and 4.
  The angle made by the hour hand when it moves from say 3 to 4 will be 30o. That is the hour hand makes 30o during the course of an hour.
  
  The hour hand will therefore, move = 20.
  
  Therefore, the net angle between the hour hand and the minute hand will be 150 – 20 = 130degrees.

• 4 1/3*360/12=130
  20*360/60=120
  130-120=10

• FOR THE HOUR HAND:
  IN 12*60 MIN MOVEMENT OF THAT IS 360 DEGREE
  FOR (4*60+20)260 MIN THAT IS OF 130 DEGREE
  
  FOR MIN HAND:
  IN 60 MIN MOVEMENT OF THAT IS 360 DEGREE
  FOR 20 MIN THAT IS OF 120 DEGREE
  
  SO ANSWER IS:130-120 DEGREE

• hour hand-------> angle------->*30
  minute hand----->angle------->*6
  4.20 convert hours=4+20/60=13/3=13/3*30=130
  minute hand=20*6=120
  hour hand-minute hand=130-120=10
