For week 25 (of the countUP) here is a neat bit of horsey maths from one of my favourite YouTubers.
I can’t think of a reason why you would need to work out
which are the three fastest out of 25 horses, but maybe you can. And anyway,
let’s suppose that’s the case.
OK, you have your 25 horses and you take them to a racetrack.
Hey, that’s a MASSIVE lorry you have. Does it need a special licence to drive
it?
The racetrack owner says, ‘Please use my racetrack but only
5 horses at a time please. Oh and I need it back, so be as quick as you can.’
Right then! 25 horses to be raced 5 at a time. What’s the
smallest number of races it will take? Go!
