Answer» Answer: At 4 O'clock, Minute hand is at 12 while the Hour hand is at 4. Again the minute hand has to sweep through ( 30 x 4 ) ie 120 o for reaching the figure 4 to show 20 MINS. We can WRITE 4 hrs. 20 mins. as 13/3 hrs. Angle traced by hour hand in 13/3 hrs =30× 3 13
=130 o
∴ Angles between hands of clock =130 degree −120 degree =10 degree Hope you GOT your answer |
