High IQ does not make you smart! Maybe a smart ass. A recent study printed in the WSJ noted that the higher your IQ the more self delusional you are. My garbage man is smarter than most PhD’s.

Rational thinking is a rare trait. We are all victims of emotion overtaking rational thought - look at the Libs, it is terminal for them.

Q1- Distance, Time, and Speed An old car has to travel a 2-mile route, uphill and down. Because it is so old, the car can climb the first mile—the ascent—no faster than an average speed of 15 mi/h. How fast does the car have to travel the second mile—on the descent it can go faster, of course—to achieve an average speed of 30 mi/h for the trip?

I'm only in the 140s (U.S> scale), but it didn't take me long to figure this one out.

The problem is lends itself to easy calculation because it uses numbers that divide easily into 60.

The whole trip is two miles (one mile up and down). At 30 mph, we know that is one mile every two minutes. That means the trip has to be completed in 4 minutes. But at 15 mph, the car takes 4 minutes to make the climb, meaning the return trip has to be instantaneous to make the 30 mph mark.

AS I said, with such questions you must get to what is actually being asked...careful attention to this will raise your score on any IQ test. This is one reason they are limited, because some people realize this and others do not.

What is asked here is, given two point separated by two miles, if it takes 4 minutes to go halfway can you cover the entire distance in exactly 4 minutes? Obviously not since even at light speed you cannot cover the remaining mile in 0.0 minutes. You could get very close but that is not good enough :-) i.e 29.99999...Avg Mph

The time factor is implicit in the phrase “average speed” i.e to have an average speed of 30mph you must cover two miles in exactly 4 minutes.

BTW, tho other question, the one that stumped Einsteins friend was this. (it seems rather simple to me)

2.Comparing Discounts Which price is better for the buyer, a 40% discount or two successive discounts of 20%?

“...scored a remarkable IQ of 162 in this summer’s University of London’s (UCL) Mensa medical test. It is the highest possible score anyone can achieve in the UK and European test.”

That’s only because they haven’t measured Joe Biden yet.

I only post on IQ threads because I like the term “standard deviation.”

“Well the I’ve enjoyed my career in Music, but now really regret ever having played a note. comment makes me sad.”

Ahh,,,, But I was born to be an Architect. Git the highest score ever achieved on the Architectural Aptitude Test. Kent State actually used my designs for a modular school building. Several were built in Ohio, and I don’t know where else. They never even informed me!

[LittleBillyInfidel]

PLEASE tell me that the correct answer is “30mph”!

[calljack]

40% discount is better

[calljack]

no it is not 30 mph

There is no answer, that’s the point of the question (which i just got (not on my own)

[allmendream]

I scored very high on an IQ test and made the mistake of speaking of “genius level IQ”, my sister said “Shouldn't you actually accomplish something amazing before speaking of being a genius?”. Yikes! I play to a tough audience!

[Dr. Sivana]

PLEASE tell me that the correct answer is “30mph”!

Nope, see post #22.

[UCANSEE2]

Exactly what I was thinking.

Now... the exact number is unknown, due to the fact that the vehicle wouldn’t really have instantaneous acceleration.

The ‘time’ might help calculate the delta of the acceleration but that would only help on the uphill side.

Time is given in both cases, as speed is defined by ‘distance and time’ (mph).

Assuming ideological (and impossible) conditions...
1 mile at 15 mph +
1 mile at x mph = (15+x)/2

(15+x)/2=y

Given y=30
x=45

So.... what are we missing ?

[Texas Songwriter]

Sheldon Cooper has a higher I.Q.

[Joan Kerrey]

meaning the return trip has to be instantaneous

I got the same answer but now I’m stumped on how I can achieve instantaneous, I’m still working on it. The car is still at the top of the hill.

[UCANSEE2]

That means the trip has to be completed in 4 minutes.

And just where does it state that the trip has to be completed in four minutes?

[UCANSEE2]

Where does it say you only have four minutes ?

Northwood College School pupil, Fabiola Mann, of Harrow on the Hill, scored a remarkable IQ of 162 in this summer’s University of London’s (UCL) Mensa medical test. It is the highest possible score anyone can achieve in the UK and European test. The 15-year-old beat physicists Stephen Hawking and Albert Einstein, who both scored 160 when they took it.

Oh, that's nothing. A couple of years back, we had a FReeper who claimed to have an IQ of 170. This same FReeper lost a $40,000 civil case, countersued the State of Washington for $15 million for being in collusion with the winning side based solely on a "knowing look", and predictably lost every appeal. He then tried to make a citizens' arrest against state Supreme Court Justice CJ Alexander, on RICO charges for not hearing his final appeal.

Let's just say that IQ numbers aren't all they're cracked up to be.

One girl said to me “This is really stupid, like attending a party where everyone writes their bra size on a name tag”
I suggested she do just that and she did, it was 34B and caused an uproar since from across the room it looked like 348 ...lol

I don't know who she is, but I like her. :)

Good/funny story, thanks for sharing it.

[James C. Bennett]

True, but this was on the UK scale, different from the US scale.

[golux]

You’ve got me scratching my head here and laughing. How can the car make it?
