### Fundamental Problem 12.45

Car **A** is traveling with a constant speed of 80 km/h due north, while car **B** is traveling with a constant speed of 110 km/h due east. (Figure 1).

#### Figure

![Traffic scenario]()

##### Diagram Description:
The diagram illustrates an intersection formed by two perpendicular roads, marking the paths of car **A** and car **B**.

- **Car A** is shown at the bottom of the diagram, moving vertically upwards (due north) at a speed of 80 km/h.
- **Car B** is shown on the left side of the diagram, moving horizontally to the right (due east) at a speed of 110 km/h.
- A vector extends from car **B**'s position to car **A**'s position, forming a diagonal path.
- The distance between the two cars along this diagonal path is marked as 2 km.
- There is an angle denoted as 45°, which likely represents the angle between the vector of car **B**'s position relative to car **A**'s position and one of the axes (x or y).

The background of the diagram includes green shaded areas indicating terrain or areas outside the roadway.

#### Conditions:
- The weather is noted as sunny with a temperature of 96°F, displayed at the bottom left.

This educational problem aims to provide a scenario for analyzing relative motion, vector components, and possibly the calculation of the time of intersection or the distance between two moving objects in orthogonal directions.
