Coordinate Geometry, a la Shmoop. Alvin, Belinda and Cletus do not get along.
- 00:13
In fact, all three have restraining orders against each other.
- 00:21
Best not to ask. Let's just say that not everyone should be allowed to own a paintball gun.

Alvin is at point A. Belinda must stay 12 yards away, and she makes sure to put exactly

that much distance between them. Cletus has to stay 18 yards away from Belinda,

and he is at point C. However... these three can't be trusted to

be left alone. Which is where Doogie comes in.
- 00:51
He's an officer who has been assigned to keep an eye on the rabble-rousers, and make sure

they don't break the terms of the restraining orders.

So he's somewhere between Alvin and Cletus.

If there are 5 yards between Belinda and Doogie, how much distance could be between Alvin and
- 01:12
Doogie? Here are your choices:
- 01:17
Well, we know there are 12 yards between Alvin and Belinda...
- 01:25
...so if Belinda and Doogie are 5 yards apart, Doogie must be either 5 yards closer to Alvin
- 01:33
or 5 yards further away from him. Looks like Doogie is 12 plus-or-minus 5 yards
- 01:42
away from Alvin... ...which is either 7 or 17 yards.
- 02:00
Hullo, Answer "E." Good luck, Doogie -- you might want to consider

wearing an athletic protector. You don't want to

catch a paintball in your... area.
