Post me your hardest maths question you know

Am I missing something here???

£2 of the £27 is his tip, it's not in addition to £27 :confused:

No.

The three men in effect pay £9 each (as they all got a £1 refund on the £10 each they paid) therefore the 3 men paid £9 each for the meal = £27 yes?

The waiter also kept £2 for himself which added to the £27 = £29 yes?

...so where'd that other £1 go?
 
What is eleventytwelve times umptyfour?

Also, is it possible to divide a restuarant bill equally between ten students when one or more of them didn't have the starter?
 
If a train is travelling at 60 miles an hour, and it passes a man carrying four oranges in one hand and six apples in the other, what is the time?

Seriously though, Simplex is probably the hardest thing i've actually 'done'. I can do this sort of thing, i just need to understand how it works, not just how to do it. Knowing why it exists helps too ;)
 
1 metre and the Segway goes 0.9r mph.
Does it ever fall off the end?

Theoretically after 1 hour, presuming you are using MilesPerHour for calculations as 1/0.9r = 0.1r

Computers mistake 0.9 recurring as 1 beacuse they have to truncate to a certain number of decimal places and then round the result. Otherwise they would need an infinite amount of memory in which to hold the infinite number of decimal places of the addition terms and the result.

If you were to put 1/0.9r into a calc it would come back as 1, but the segway would fall off but it would be completely dependant as stated on other variables such as the distance,friction etc.. :) if you want to get technical but yes it would fall off EVENTUALLY it could take seconds, minutes,years,lightyears, perhaps a number we can yet comprehend but it would happen :)
 
How about this one -

You travel to america at 100km/h. You then travel back at a constant speed. The average speed for the entire journey is 50km/h. What was your speed in returning from america?

heh heh heh
arent i funny

LOL yes very funny.....

Same speed as this racing driver on his 2nd lap:

A racing driver had to have an average speed of 60mph across two laps in order to qualify for a race - he had engine trouble on the first lap so only managed and average of 30mph - how fast does he have to travel on the second lap in order to have an average speed of 60mph across both laps.

What part of America.

erm what?

You've phrased that slightly wrong I think.

He needs a speed of 90mph to average 60mph over the two laps, however, doing so would not allow him to qualify for the race.

What I think you intended to ask was: A racing driver had to have an average speed of 60mph across two laps in order to qualify for a race - he had engine trouble on the first lap so only managed and average of 30mph - how fast does he have to travel on the second lap in order to qualify for the race?
