How about another question:

If the time is 3:15, what's the angle between the hour hand and the minute hand ??

As in degrees of a circle. For example, a right angle (at 3:00) would be 90 degrees.

o and BTW the answer was wrong...it was actually:

M dog/cat= O/P
N dog/cat= M/O
O dog/cat= P/N
P dog/cat= N/M

and i have another one of these on my midterm but a little different and a little longer...at least he already gave it to us. But damn i hate these things

Did you find out why the other answer was wrong? I think there can be a couple answers. Just because it wasnt the EXACT one the teacher had doesnt mean you werent right.
