Know that I'm tired, but surely this is zero degrees? As the hands are both together...

7.5 degrees.....

Well, each minute mark is 6 degrees, and the hour hand will move 6 degrees every 12 minutes.

So in 15 minutes, the hour hand has moved 6 + (3/12)(6) = 7.5 degrees. And since the minute hand is now exactly on the 3, the distance between them is the same.

7.5 degrees

Better than taking a wild guess at 180 degrees tho' :whistling:

Wasnt a wild guess as 180 degrees is a straight line:thumbsup:

7.5 degrees

but then sureley 7.5 is just the amount of degrees the hour hand has moved to get to the same position as the minute hand, not the actual distance between them

Here is my logic.

At 3:00 the hour hand would be exactly on the 3.
At 4:00 the hour hand would be exactly on the 4.

So in 1 hour the hour hand moves 1/12 of the way round the clock. 1/12 of 360 is 30 degrees.
In the 15 minutes from 3:00 the hour hand will have moved 1/4 round the clock (and be pointing exactly at 3), and so the hour hand will also have moved 1/4 of the way between 3 and 4. Therefore the angle between the hour hand and the minute hand is 1/4 of 30 degrees.

So 1/4 of 30 degrees (angle between 3 and 4) is 7.5

I did it in my head in a matter of seconds, do people really find simple stuff like this hard to do? Is that a reflection on the state of British education these days?
