What is the number of degrees that the hour hand of a clock moves through between noon and 2.30 in the afternoon of the same day?
A. 360
B. 180
C. 90
D. 75
E. 60
The hour hand moves from pointing to 12 to pointing to half way between 2 and 3. The angle covered between each hour marking on the clock is 360/12 = 30. Since the hand has covered 2.5 of these divisions the angle moved through is 75.
