Total degree it moves in 12 hours=360 degree
total degree between 1 hour =30 degree 
between noon that is 12o'clock and 2:30 there are 2 and a half hours.
so it turned 2 1/2 x 30= 75 degree
so the hour hand moves 75 degree between noon and 2:30 in the afternoon.

360° is completed in 1 hr or 12 markings.
360/12=30
This means 1 marking or 5mins are 30°.
The clock moves between noon and 2.30 in (30×2)+(30×0.5)
⇒60°+15°=75°

Ans=75°
