Let’s rephrase this for Calvin. The female brain is twice as far away as the male brain. If the female is 5 feet away from the male, how far do you need to shuffle to get to the male brain?

If A, B, & C are on a line AC is either 10 or 10/3 (which is ~3.33). If the three points are on a plane then there are an infinite number of answers between 3.33 and 10.

I think I just solved it. Assuming that the points are on a straight line, we have A-B-C, where each dash represents 5 inches. Therefore, A—C=10 inches.

there isn’t enough information in the question to solve the problem. It’s easy to solve if the 3 points are arranged in a straight line (the answer would be 10) But it doesn’t say that, if the 3 points are arranged in a triangle then you would need to know at least one of the angles of the triangle to solve the problem.

This is a clever puzzle. The square of AC follows an elliptical path as the angle between AB and AC varies. HIgh school math but a little beyond poor Calvin.

The answer is 10 inches if you assume you go from point A to point B to point C in a strait line. We see that Calvin does not go from point A to point B or anywhere in a strait line.

## debra4life over 5 years ago

The question didn’t say whether the 3 points were in a straight line or in a triangle….Makes a big difference.

Simple really

## Charliegirl Premium Member over 5 years ago

I never could “get” those kinds of problems!

## orinoco womble over 5 years ago

Wait…is the brain show and tell arc over? Just like that? Did I miss something?

First: BC=5 AC=2BA, insufficient data; second: Watterson majored in Political Science.

Yup. Maths is evil… It creates deadites…

Wow! I forgot about the zombie mode. Calvin was wayyy ahead of his time for the latest zombie fad. Good stuff!

## AlanM over 5 years ago

All solutions are on a circle. If B is at 0,0 and C is at 5,0 then it’s a circle with a diameter of 6.67"

Goto http://www.wolframalpha.com/examples/Math.html and enter this into Plot sqrt(x^2 + y^2) = (sqrt( (5-x)^2 + y^2))/2

OMG! Not Math Class!!!

## walk.rich over 5 years ago

Solutions are: 10 or 1.66 if all points are on a straight line (ABC or BAC).

NAH!!

If Calvin put as much ingenuity into his homework as he does in finding ways to avoid it, he’d be Stephen Hawking.

I think this arc (about a year or so into the strip) was where C&H began to hit its stride.

## alondra over 5 years ago

In this I don’t blame Calvin one bit. Those story problems are murder! One reason to be so glad to be out of school.

## KEA over 5 years ago

glad to observe that so many (but bit all) C&H readers are mathematically adept.

## battycomic Premium Member over 5 years ago

I would say that the answer is 10 inches.

Just like “I before E except after C” or whatever.

That is obviously a American thing because I have never heard that kind of nonsense in the UK.

Haha.
