GAME: Brain Teasers

Post by UBT - Chris » Sat Dec 13, 2014 1:13 pm

This thread is for brain teasers - if you have a QUESTION for answering, put Q1, Q2, etc. (in order), and if you are answering a question, put A1, A2,etc (again, in order).

E.g:

Q1: how many apples does jack have if he has 4 apples less than joe, who has 2x more than albert, who has 8?

A1: 12 apples.

This process gets repeated.
Each Q can only be answered once, but if it is incorrect, somebody else may answer it.

I'll start...

A fun idea Chris, I totally failed on question 1 though. :oops:

So now let me ruin it for everyone with this, one of my favourite little maths teasers.

Q6. I drive my old Ford Focus around a mile long race circuit and finish the lap with an average speed of 30mph, I decide to do another lap of the same circuit, but how fast do I need to go on this second lap if I want to complete both laps at an average speed of 60mph?  :scratch:

This is annoying me! I thought it was 90 MPH but I'm sure it's not that easy - I'll get it...

Steady on I'm still trying Josh's!

A6

My head hurted thinking about this one - right I've got it, it's defo not 90. It's such a sneaky question I'm not going to spoil it by giving the answer obviously.

Hopefully this is white on white! It's impossible as you've all ready taken 2 minutes to do the first mile, to average 60MPH over 2 miles you'd need to do both laps in 2 minutes, as you've all ready taken 2 minutes to do the first you'd have to do the second instantly!

Tim - can we move this thread to the Team Cafe section?

I think we need to have a couple of rules for this.

1 - Quote original question in the answer - otherwise it's gonna get confusing when other members post questions before others are answered.

2 - Don't post your answers too quickly - we need to give other people a chance to answer and make their brain hurt! So something like allow 6 hours before answers are given even if they're wrong!

or

if you have to give an answer you could post your reply as white text on a white background?

that's why I wasn't too sure - it could be 120, maybe, but it is logical for it to be 90: 30mph+90mph = 120mph/2 = 60 = avg...
