The circle is 360 °.
1 circle for the clockwise is 12 hours, therefore 1 hour = 360 ° / 12 = 30 °.
1 hour is 60 minutes, therefore for a clockwise direction 1 minute = 30 ° / 60 = 0.5 °
Then the 21 ° hour hand passes in 21 ° / 0.5 ° = 42 minutes
For the minute hand, 60 minutes is 360 °, i.e. 360 ° / 60 = 6 ° – one minute.
6 ° * 42 = 252 °
Answer: 252 °
