Isn't question 4 719?
This means that when done in reality there would never be more than 4 people in the revolving door at any given time (as you would have to purposely miss the exit to ever get to the third segment).
I didn't like 4, it assumed at the start the compartments were all full, and a complete rotation in the timeframe (stopping at the end) means anyone still in the door got through?
Then i realised i was over thinking it a tad.
They do little reading 1 on 1 with the teacher as I used too, they expect this to be done with the parents.
Good, I strongly believe reading to your kids when they're young / getting them to read massively affects their educational progress.
I obviously only have anecdotal evidence, but i think parents should have to be doing this, if teachers do it then it's just a bonus.
Of course but then the teachers should do it too, but the class sizes are way too large so they can't give kids the 1 on 1 that lots of them require.
Last week in our Cambridge Evening news there was reception photos of all the schools in cambridge. Some of the class sizes was staggering. Would the 680m just being spent on free school dinners not be better spent on more teachers?
I skipped 2 years of school.
I has no GCSE's at all because I never took any.
I have a learning difficulty a pretty major one.
yet still find the above questions pretty simple and straight forward.
most of them you can only fail from having no reading comprehension.
seriously my 8 year old has homework a lot like the above questions 1-3 , how the hel can a 15 year old fail unless they did not try or randomly picked an answer
Your working out is flawed, the answer is 720 as every 5 seconds 2 people can enter the door.
30mins in seconds is 1800 seconds.
1800/5 = 360 chances for 2 people to enter the door.
360 chances x 2 people = 720 people.
What else would you use?
I picked 720 for the answer.
I haven't done the maths but I believe the actual number should be either 718 or 716.
I'll leave it someone else to explain.
Because you dont know or cant be bothered?![]()
I'm not amazing at Maths and got 5/6, I got the last question wrong, can anyone show me the working out?
I can't be bothered to do the maths precisely.
Basically in the first 5 seconds no-one gets in because they're still in the door. In the last 5 seconds two people could still be in the door. Therefore either 2 or 4 people don't make it inside in the 30 minutes.
