Q1. Time was 3:15 in the clock write an code to find the angle between the hour and minute hand
Ans. 
Calculate the angle between the hour and minute hands of a clock at 3:15.
• Each hour on the clock represents 30 degrees (360 degrees / 12 hours).

• Each minute represents 6 degrees (360 degrees / 60 minutes).

• At 3:15, the hour hand is at 97.5 degrees (3 hours * 30 + 15 minutes * 0.5).

• The minute hand is at 90 degrees (15 minutes * 6).

• The angle between the hands is the absolute difference: |97.5 - 90| = 7.5 degrees.
