**Velocity Function and Displacement Analysis**

In the context of velocity and displacement, we consider a scenario where two cars are traveling, and we aim to estimate the time at which they are again side by side.

**Question**: Estimate the time \( t \) (in minutes) at which the cars are again side by side.

**Input**: 
- An entry field for time estimation, currently showing \( t = 2 \) minutes.
- A feedback section labeled "Enhanced Feedback" that guides the user to reconsider their estimation.

**Key Concept**: The definite integral of a velocity function over a given interval represents the total displacement. To determine when two cars are side by side, one must compare their displacements, factoring in the areas under their respective velocity-time graphs. A greater area under the curve translates to a greater distance traveled by a car.

This exercise highlights the application of calculus in real-world motion problems, aiding students to comprehend the relationship between velocity, time, and displacement.

The image shows a mathematical problem involving two cars, A and B, starting side by side and accelerating from rest. The accompanying graph illustrates the velocity functions of the two cars.

### Graph Details:
- **Axes:** The horizontal axis represents time \( t \) in minutes, while the vertical axis represents velocity \( v \).
- **Curves:** 
  - **Curve A (Blue):** This line shows an initial rapid increase in velocity before tapering off, suggesting higher initial acceleration.
  - **Curve B (Red):** This line increases at a more constant rate, indicating steady acceleration.
- **Intersection:** The two curves intersect around \( t = 1 \) minute, implying that both cars have the same velocity at that moment.

### Explanation:
The graph demonstrates how the cars accelerate differently over time. Car A starts with a faster acceleration compared to Car B, but Car B eventually reaches the same velocity as Car A and continues to increase its speed steadily. This type of analysis helps in understanding concepts related to motion, acceleration, and velocity in physics.
