Magic Belt

[classic33]

A man is pushing his car along the road when he comes to a hotel. He shouts, "I'm bankrupt!" Why?

 

[classic33]

Which weighs more, a pound of feathers or a pound of bricks?

Why is Rebecca(she's back) now five miles away from all of us, at the same time?

Because no-one likes her and everyone gives her a wide berth.

Messy divorce.

Well, as much as a £ of feathers would get you, I reckon by mass a £ of brick would weigh more, so B.

He is playing Monopoly.

I have this but it seems too easy so there's probably a naughty landmine in the question....

How did you get 96 cm?

They weigh the same (one pound).

Because no-one likes her and everyone gives her a wide berth.

But how does she manage to be the same distance from everybody at the same time?

How did you get 96 cm?

Working in reverse:

For Width

1. 9 / 3 = 3 (9 is the original width given)
2. 3 / 3 = 1
3. 1 / 3 = 1/3

For Length

1. 4 / 1/3 = 12 (4 is the final area given so 4 divided by a third is the final length)
2. 12 x 2 = 24
3. 24 x 2 = 48
4. 48 x 2 = 96

This is how I did it :
Initial Surface Area SA0 = len x wid
After one wish Surface Area SA1 = len/2 x wid/3 = (len x wid)/6
After two wishes SA2 = len/4 x wid/9 = (len x wid)/36
After three wishes SA3 = len/8 x wid/27 = (len x wid)/216
Therefore we can say SA3 = SA0/216
But, we know SA3 is 4, so 4 x 216 = SA0 => SA0 = 864, but we know wid = 9, therefore length = 864/9 = 96cm

Ah - I stopped at 2 iterations and had a width of 1cm, instead of one-third

[QUOTE 2587694, member: 259"]Did you get fooled by only doing two wishes, not three? I know I was.[/quote]
Yes, exactly that.

 

[swee'pea99]

I don't care.


Correct!

How could you practically travel over 14 minutes & 15 seconds in 12 minutes & 30 seconds?

I reckon whoever was wearing the belt would be squeezed to death after three wishes
