Angle formed by hour hand in an hour = 30°
Angle formed in 2 : 15 hours [9/4 hour]
$=\frac{9}{4}\times 30°=\frac{135°}{2}$
Angle formed by minute hand in 60 minutes = 360°
∴Angle formed in 15 minute $=\frac{360}{60}\times 15=90°$
∴ Angle formed by hour and minute hand$=90°-\frac{135}{2}$
$=\frac{45}{2}=22\frac{1}{2}$
