Introduction

In this article, we will explore a scenario where two friends, Greta and Shayla, are biking on a trail. Greta starts at mile marker 5 and is biking at a speed of 12 miles per hour. We are given a table that shows the mile marker Shayla reaches after biking $x$ hours. Our goal is to find the difference in the initial values of the two friends' positions on the trail.

The Problem

Let's break down the problem step by step. We know that Greta starts at mile marker 5 and is biking at a speed of 12 miles per hour. This means that after $x$ hours, Greta will have traveled a distance of $12x$ miles. Since she starts at mile marker 5, her position after $x$ hours will be $5 + 12x$ miles.

On the other hand, we are given a table that shows the mile marker Shayla reaches after biking $x$ hours. Let's assume that Shayla starts at mile marker $a$. Then, after $x$ hours, Shayla's position will be $a + bx$ miles, where $b$ is her speed in miles per hour.

The Table

The table shows the mile marker Shayla reaches after biking $x$ hours. Let's take a closer look at the table:

$x$ (hours)	Mile Marker
0	0
1	3
2	7
3	12
4	18

Analyzing the Table

From the table, we can see that Shayla's position after $x$ hours is given by the equation $a + bx$. We can use the table to find the values of $a$ and $b$.

Let's start with the first row of the table, where $x = 0$ and the mile marker is 0. This means that Shayla's position after 0 hours is 0 miles, which is equal to $a + b(0)$. Therefore, we can conclude that $a = 0$.

Now, let's look at the second row of the table, where $x = 1$ and the mile marker is 3. This means that Shayla's position after 1 hour is 3 miles, which is equal to $a + b(1)$. Since we know that $a = 0$, we can substitute this value into the equation to get $0 + b(1) = 3$. Solving for $b$, we get $b = 3$.

Finding the Difference

Now that we have found the values of $a$ and $b$, we can find the difference in the initial values of the two friends' positions on the trail. Greta starts at mile marker 5, while Shayla starts at mile marker 0. Therefore, the difference in their initial positions is $5 - 0 = 5$ miles.

Conclusion

In this article, we analyzed a scenario where two friends, Greta and Shayla, are biking on a trail. We used a table to find the values of $a$ and $b$ in the equation $a + bx$, which represents Shayla's position after $x$ hours. We then found the difference in the initial values of the two friends' positions on the trail, which is 5 miles.

This problem involves several mathematical concepts, including:

• Linear equations: We used linear equations to represent Shayla's position after $x$ hours.
• Graphing: We could have graphed the equation $a + bx$ to visualize Shayla's position after $x$ hours.
