If you look at a clock and the time is 3:15, what is the angle between the hour and the minute hands?

so what is the angle? Something in the 350 degrees range, I'd reckon, right?

Depending on the interpretation, either 0 or 360º when you consider it. If you look at it as travel from the origin point with both hands at the same point, it's 0º. If you start at the origin and follow around to the minute hand, it's 360º

Thank you all for the wonderful answers. You all get an A++. However, the question was asked of Chipy and I have not received an answer yet. I have a feeling he doesn't love us anymore folks.

True in general, but at 3:15, the hour hand would theoretically be 1/4 the way from 3 to 4 right, so it wouldn't line up with 15 on the minute hand anymore. More like 3:16 or so, no?

7.5 degrees.

minute hand is at 90 degrees, hour hand is at 90 + (360/12)*(1/4)

I'd go 352.5 degrees based on the original wording of the question, but thanks for doing the math, I was too lazy.

More interesting to work out how long it is before the hands overlap again.

"More interesting to work out how long it is before the hands overlap again."

The limit of the series: 1 +1/12 +(1/12)^2 +(1/12)^3...... hours

= a little more than 1 hour 5 minutes and 27 seconds

Hey, I just thought of another way. Between 12 and 12, this happens 11 times, so it happens every 12/11 hours. I checked the math, it gives the same answer.

But how long does it take for the minute hand to lap the second hand, from your frame of reference, when it is on a spaceship traveling away from your at 95% of the speed of light?

I'm not sure, but I know it is past time for me to go to bed. G'nite!

But that doesn't tell you how long between the current time and the next overlap.

It's always the same. Think of the hands as two race cars going around a circular track, each at a constant speed, where one is twelve times faster than the other. It always works out to 1.091 hours ( 1:05:27)

When it is 3:15 in this room, it's typically about 70 degrees.

I'm not sure, but I know it is past time for me to go to bed. G'nite!

t' =t * sqr(1-v^2/c^2) = t * sqr(1 - (0.95^2/1^2)) = t*0.312

1.091 hours / 0.312 = 3.5 hours

I think this is right, but I wouldn't bet the house on it.

Oh, I think what you are doing is awesome! Keep up the good work.

However, I'm beginning to think Chip doesn't know the answer. The man isn't right in the head.
