What is the angle between the hour hand and the minute hand of a clock at 3:30?
Answer: B
The formula for the angle between the hands of a clock is \(|30H - \frac{11}{2}M|\), where H is the hour and M is the minute.
Here, H=3 and M=30.
Angle = \(|30(3) - \frac{11}{2}(30)| = |90 - 11 \times 15| = |90 - 165| = |-75| = 75°\).
