Here’s a question that will help you get your shmoop on…

00:06

If it takes one of the king’s horses 40 minutes to put together Humpty Dumpty…

00:10

…how long will it take for three of them working on it together?

00:14

Assuming they’re not… you know… all hooves?

00:17

And here are the potential answers...

00:23

So… this question makes a big fat presumption that too many cooks aren’t spoiling the kitchen…

00:28

and that 3 horses work 3 times as fast as one.

00:32

But if we look through that likely falsehood, logically, if 40 over 1 minutes is how long

00:37

it takes one horse to assemble an oversized omelet…

00:41

…then it takes 40 over 3 minutes for 3 horses to do it.

00:48

If we scan the answers, we note that 3 over 40 – answer A – has to be wrong because

00:53

it can’t take just a few seconds…

00:55

So we’re gonna say… neigh.

00:59

The other answers reduce into minutes and seconds – so 40 divided by 3 is 13 and a

01:04

third – and a third of a minute is 20 seconds… so we’re good with B.

01:10

B, as in… “Better call for backup.”
