Understanding the Problem

When it comes to modeling real-world situations with inequalities, it's essential to understand the context and the relationships between the variables involved. In this case, we're dealing with the maximum speed on a highway, which is set at $55 \, \text{mi/h}$. We need to create an inequality that represents this situation and accurately models the relationship between the speed and the maximum allowed speed.

Analyzing the Options

Let's examine the options provided to determine which one accurately models the situation:

Option A: $s \geq 55$

This option suggests that the speed $s$ is greater than or equal to $55 \, \text{mi/h}$. However, this doesn't accurately model the situation, as it implies that the speed can be equal to or greater than the maximum allowed speed. In reality, the speed should be less than or equal to the maximum allowed speed.

Option B: $s \leq 55$

This option suggests that the speed $s$ is less than or equal to $55 \, \text{mi/h}$. This accurately models the situation, as it implies that the speed should be less than or equal to the maximum allowed speed. This option ensures that the speed is within the safe and legal limits.

Option C: $s \ \textgreater \ 55$

This option suggests that the speed $s$ is greater than $55 \, \text{mi/h}$. This does not accurately model the situation, as it implies that the speed can be greater than the maximum allowed speed. In reality, the speed should be less than or equal to the maximum allowed speed.

Option D: $s \ \textless \ 55$

This option suggests that the speed $s$ is less than $55 \, \text{mi/h}$. While this option implies that the speed is below the maximum allowed speed, it does not account for the possibility that the speed can be equal to the maximum allowed speed.

Conclusion

Based on the analysis of the options, the correct inequality to model the situation is:

$s \leq 55$

This inequality accurately represents the relationship between the speed $s$ and the maximum allowed speed of $55 \, \text{mi/h}$. It ensures that the speed is within the safe and legal limits, and it accounts for the possibility that the speed can be equal to the maximum allowed speed.

Real-World Applications

Modeling real-world situations with inequalities is a crucial skill in mathematics and other fields. In this case, understanding the relationship between speed and the maximum allowed speed is essential for ensuring public safety and preventing accidents on the highway. By using inequalities to model this situation, we can create a mathematical representation that accurately reflects the real-world constraints and relationships.

Additional Examples

Here are a few additional examples of how inequalities can be used to model real-world situations:

• Modeling Temperature: Suppose the temperature in a room is not allowed to exceed $75^\circ \text{F}$. We can model this situation using the inequality $t \leq 75$, where $t$ represents the temperature in the room.
• Modeling Time: Suppose a project has a deadline of 10 days. We can model this situation using the inequality $d \leq 10$, where $d$ represents the number of days the project has been ongoing.
• Modeling Distance: Suppose a car is traveling at a speed of $60 \, \text{mi/h}$ and has a maximum allowed distance of $200 \, \text{mi}$. We can model this situation using the inequality $d \leq 200$, where $d$ represents the distance traveled by the car.

Conclusion

In conclusion, modeling real-world situations with inequalities is a powerful tool for creating mathematical representations that accurately reflect the relationships and constraints involved. By using inequalities to model situations such as highway speed, temperature, time, and distance, we can create a deeper understanding of the underlying relationships and constraints.
