This question is racking my brains!

I think it's simple but I just can't seem to do it!

If six teenagers can gobble up 12 pizzas in an hour, how many
teenagers will it take to eat 6 pizzas in an hour and a half?

Any ideas?

I'm getting 1 and a half teenagers, thus I'd guess it's 2.

EDIT -> Yes the answer is 2. It was a moment of pure stupidity on my part, I tried to work it out using formulae that were not required, lol.

I'm going for 2.

???

2 teenagers.

pretty simple stuff.

12 pizzas in 1 hour, so 6 pizzas in 1.5 hours is the equivalent of 4 pizzas per hour, which is 3 times less than 12 pizzas, so you divide 6 by 3 to get 2 teengers

I did this...

6 eat 12 in an hour

so 3 can eat 6 in an hour

they've got 50% more time so half again = 1.5

That right?

they dont have double the time, so you dont do the final divide by 2, you would multiply by 2/3

I did 1 teenager can eat 2 pizzas in an hour.

So in an hour and a half 1 teenager can eat 3.

6 pizzas in an hour and half - 2 teenagers.

6 eat 12 in an hour
so 1 would eat 2 in an hour
ie it takes 1/2 hour for each person to eat a pizza
in an hour and a half each person can eat 3 pizzas
hence it will take 2 people to eat 6 in an hour and a half

Ok, six teenagers can eat twelve pizzas in an hour. So that's two pizzas per teenages, per hour.

Give one teenager an hour and a half, and they'll eat three pizzas.

We want enough teenagers to eat six pizzas in an hour and a half - so you'll need two.

I divided by 2 because they have 50% more time. I'm pretty sure that's right.

Anyone got some spare pizzas and spare teenagers? Lets try it.

Mulder · 3 Feb 2006 at 15:37

Please forgive my stupidity, it's friday. The answer is 2.

Raikiri · 3 Feb 2006 at 15:37

It is 2

12 in one hour = 5 min per pizza

6 in 90 mins = 15 minutes

It takes 3x as long, therefore there are 1/3 of the amount of teenagers

NokkonWud · 3 Feb 2006 at 15:38

I worked it at 2 people.

Wryel · 3 Feb 2006 at 15:40

Hmmm, don't think I could eat 6 teenagers in an hour and a half.

The_blue · 3 Feb 2006 at 15:46

12pizza /6kids = 2 pizza per hour each kid

6 pizzas is 3 hours work for 1 kid

3 hours / 1.5 hours = 2 spotty kids

Does this not depend on external influences factors such as :

size of pizzas
nationality of teenager
sex of teenager
type of toppings
thin crust / deep pan?
Stuffed crust?
distance of pizza shop from pizza eating venue
size of moped engine of pizza delivery boy

Then again, it's probably 2.

FeFiDoh · 3 Feb 2006 at 16:22

how many peices does the mere cat get??

Probably matters more on the ethnicity of the teenagers, not the nationality. And Religion. Jews/Muslims can't have salami pizza, more for me
