Miss MaryDoll’s mischievous mathematical machinations ???

Miss, I’m stuck. Thought it was 6 but can see other people’s answers?

Sorry Miss, I forgot we were back to school today . I haven't cheated Miss, honest, I've just looked at the puzzle and worked out the answer. Which is 7.5 I reckon.

Now I'm going to look back and see if there is another puzzle...

The answer to the second one is 9, because we've all got the same sister. And a mum and dad. So 6 boys, 1 girl, two grown ups

7.5 and 9

Oops! Late again. Sorry Miss
As it’s a mischievous class today does that mean I can be naughty?

I will settle down now and do the questions without copying. Promise ?

Not looked at anyone’s which is probably why I make it 7 ½ and am probably completely wrong. ?

Number two I make 9 including parents.
Now I’m off to check what others have said.

Miss, Miss, callistemon’s been eating chocolates in class ?

squiffy when are you bringing your dog in again? ?

When it's house-trained Doodle!

Oh yes ok. Good plan ?

Doodle stop telling tales to Miss.
Would you like one? Just the one, mind!
You can pss them round to everyone.

Here and ready for action!

Busy day on the phone yesterday. Someone we know died of Coronavirus over the weekend. A very sweet man in his eighties. He contracted the virus in February, while in hospital recovering from pneumonia of all things..., so the poor man never even had a chance.
The family is devastated because they can't get him back for a proper burial or funeral service. There will be a virtual prayer vigil and a candle lighting tomorrow. Anyway, we got the news yesterday and I didn't have the will to do much of anything.

So, to the problems at hand:

Clock - At 3:15, the Minute hand will be at 90 degrees and the Hour hand at 97.5 degrees, the difference is 7.5 degrees

Answer: 7.5 degrees

Some younger people don't even know how to tell time. They have to look at their cell phone....which reminds me of a joke about two Millenials trapped in a (vintage) lift with only a rotary phone for emergencies. They couldn't call for help because the instructions for use were written in cursive!

Family puzzle:
There are 9

Oh Wila, thank goodness you are here. We were worried, when you weren't posting.

I was about to post the solution, but as always, you have come up trumps!

What sad news for you. A virtual hug is on it's way. It's hard enough, without actually knowing someone who has dided from the virus. ?

ANSWER: 7.5 degrees.

EXPLANATION: When it is 3:15, the hour hand will be on the 3 while the minute hand will be one quarter of the way from the 3 to the 4 (since a quarter of an hour has passed). There are 360 degrees in a circle and 12 numbers on the clock therefore there are 30 degrees between the 3 and the 4. With the hour hand a quarter of the way between the 3 and 4 and the minute hand exactly on the 3, the two hands are separated by 30/4 = 7.5 degrees.

I think Wila's is a far easier solution to understand.

Answer: 9.
Two parents, six sons, and one daughter. All of them have one sister (not six sisters).

Thanks all for giving it a go. See you all tomorrow.

Glad you came in Willa it means I’m not last in most days. Sorry you have lost someone to this virus. Take care
