think about it

6:40 to 8:40 That's 2 hours

8:40 to 8:55 that is 15 minutes. 

hence 2 hours and 15 minutes.  

Thanks Alan,

Thanks for the address too - it is a really good idea to reference posts like this.  

I used the link and examined your previous post and I would have arrived at the same answer but I have always maintained that there are differerent levels of understanding.  

I think Chris and I both  accept this answer but I think I only understand it at a superficial level.

Is there anything you can say that will help?  Maybe I just need to think about it and work through a few different shapes to cement an understanding.  Yes, that should work.

Don't worry, I am just thinking with my fingers.  

Thanks David.  

There ARE a lot of them.

Hi everyone,

I am using a new heading - I am hoping that it will stand out better in the forum.

Another busy day with lots of fantastic answers from Mathwizard91472, CPhill, Bioschip, garanceme, Alan, DavidQD, Bertie, and 1or 2 anonymous people.  A big thank you to all of you.  

There was only one unanswered question on the forum and I am sure Chris will have answered it by the time I finish this post.  Andre, Chris has got his eye on the admin score on the 'Top Answerer' board, it shouldn't take him too long to over take! Then it will be my turn to worry. lol

There were also a couple of nice thank yous given today,  all answerers really appreciate it when people show their gratitude.  

I like this question today.  It made me think.  Chris and I both invite more comment.

This one also generated interest.

Chris has told me that sometimes these links don't work.  There are still a lot of teething problems on the new forum.  I think they usually work though. So good luck.

That is it for this lovely Saturday/Sunday

I don't know why it is lovely - I am just in a good mood.

Thanks Chris,

Our anonymous enquirer should change it to a mixed numeral i think.

I really like the way you explain these questions Chris.  I probably should try to adopt a similar method. 

Thanks Chris,

I was struggling with this question.  

I guessed that  

$$V=540\times\left(\sqrt{\frac{1600}{900}}\right)^3$$

but you helped me understand why this is correct.

If anyone else would like to put another take on it i would be very interested. 

thanks Chris, I just want to clarify

$$\sqrt4 = +2$$

Since the square root was in the original question the answer is positive

Chris DID say this, I just wanted to stress it.

Thank you - We really appreciate it whe people say thanks. 

(You got 4 more points too - 3 from me and 1 from someone else, probably another answerer)

That is the BEST type of diet. 

It wasn't a criticism Alan.  It is just that the students often forget, or get confused, so I like to remind them.  That is all.
