Nabu's Knee-knocker
This is the map of a neighborhood where
all the streets are east-west or north-south. The taxi-distance between
two intersections in this neighborhood is the length (measured in
blocks) of a shortest route between the two points. All routes must
follow the streets like a taxi-cab would go. For example, the taxi-distance
between points A and B is 5 blocks.
The Library in this neighborhood is at an intersection. Here are clues
about the location of the Library (L).
Clues:
- Taxi-distance from A to L + Taxi-distance from B to L = 7.
- The Library is closer to A.
- B is closer to the Library than to A.
- When you are at A and go to the Library, you do not need to
make any turns.
Can you locate the Library?
