It was 4’o clock in the evening. Shilu was staring at the new watch that was presented by her Dad two day's ago. She was trying to measure the exact time between 4 and 5’o clock during which the hands of the watch point in opposite directions forming a straight line. What would be that time?

(a) 45 minutes past 4 (b)40 minutes past 4 (c) 50 4/11 minutes past 4
(d)54 6/11 minutes past 4.

• answer is 54 6/11
  easy method is by using the formula |30H-(11/2)M|=degrees
  |30*4-(11/2)M|=180 =>By solving, we get 54 6/11

• ans) d
  when 2 hands are in opposite directions they are 180/6=30 minutes apart. ow
  we know the formula (5h*12/11) [where h is the initial time]
  here initial time is 4'o clock. we multiply 5*4=20
  now we add 30 minutes with 20 (20+30)=50
  according to the rule (50*12/11)=54 6/11 (ans)

• this the problem related to clocks
  angle=[11/2M-30H]
  here angle=180,H(hrs)=4
  so
  180=[11/2M-30*4]
  by solving this u get 54 6/11
