It would make much more sense to talk about racing the person outside of the pool to the edge of the pool or something like that, because there's no information regarding how fast you can lift yourself (or walk if there are steps) out of the pool, etc. That being said, calling a relatively difficult SAT math question "High IQ" did make me smile 
It's a difficult question, because you have to first reason about what your optimal starting point is, what the guard's optimal starting point is, whether you're changing direction mid-stream and so on. And even if you find an escape using one scenario you have to prove it's an optimal scenario of some sort.

If you grab the life-guard by the ankle, he will probably slip and fall, breaking his hip. You will then be able to escape pretty freely, but then suddenly realize that the life-guard isn't there to keep you in the water, but to help you in case you drown. Oh no, what have we done? That guy is just doing his job! You are like the fifth person who wants to inujure or kill the poor guard I just realized there is a shitton of really cruel people on TL...
In justification of the scenario I imagine that I am an old Jewish man trying to relax in a pool in burgeoning Nazi Germany. The 'guard' is a member of the Nazi Youth, not wanting to get his stupid uniform wet and patrolling around the pool shouting slurs at me and telling me how he's going to beat me up when I come out of the pool. I'm not necessarily a violent person or wanting to really injure him, but as a matter of self-preservation I know his threats are real and I'm not going to feel that guilty if he hurts himself when he slips.
To me the question of the op was one of thinking outside conventions and picking out the actually important details. If it was just a math problem, why have the story about the pool? Most people seem to have decided the context and actual problem are not the important part of the question. In order for the mathematical solution to be realistic, it would have to be more like a video game, where one player or the computer is the guard and can cover a small amount of the border, and the other is a little dot inside the border that moves at a third of the speed. But that's not the same question, even if it is an interesting question.

or he caught u in the pool with a dead body and u gotta get away before the cops show up
that's the scenario i was imagining

I'm more along the lines of "drunk skinny dipping in the public pool at night" It is breaking and entering and therefore the guard wants to get a hold of me and called the police so I have to get out and run ASAP. Obviously I was in the pool with a girl but she got out before me and is hiding in the bushes somewhere.
No blood, breaking of limbs or killing involved

That was a fun one.

I tried it as well, took me like an hour using notepad. 
But in my defense, at some point I got stuck trying to do "what-if" scenarios wasting a lot of time.
By the way, I did a class on logic solvers for university, and these problems are very easy to define using almost pure boolean logic (with natural numbers extension). For instance, here you would need 5 arrays for each of the labels a house can have, then you would use a pre-set function demanding that the array is bound 1..5 and that every value is unique. Then you can say that e.g. Pet[0] = Color[3], and if there is a unique solution it will find it in less than a second.
