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

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

To answer many of your questions...

1) The teenagers are all clones of the original teenager, thus, no differences arise there. (and also had identical upbringings so their phenotypes are the same too

)

2) The pizzas are all uniform, exactly the same weight, dimension, "filling up value" etc

3) The teenagers eat at a constant speed, unaffected by what they have previously eaten or are anticipating to eat.
