- Angle traced by the hour hand in 18 hrs =360
Angle traced by it in 15 hrs 50 min(140/9 hrs)=(360/18)(140/9)=311.11
Angle traced by the minute hand in 90 minutes =360
Angle traced by it in 50 minutes=(360*50/90)=200
Required angle=311.11-200=111.11=111

- Angle made by hour hand in 1 hour = 360/18
and by minute hand in 1 minute = 360/90
So the angle made by clock while the time is 15:50 is ((360/18)*15+(360/18)*(50/90))-(50*4)=111
