Interview Question: Telling the Time

Sample Question #168 (brainteaser)

What’s the angle between the hour and minute hands when the time is 3:15?

(Comment: this question, for inexplicable reasons, is extremely popular at job interviews)

(Comment 2: because this is really an easy question, you should answer it by logical deduction, without drawing a clock face on paper)

    ANSWER
     
    At 3:15, the minute hand is on the number 3 while the hour hand is 1/4 of the way between 3 and 4. The angle between any two numbers on the clock face is 360/12 = 30 degrees, so the final answer is 30/4 = 7.5 degrees.
