Introduction
In the world of mathematics, problems often present themselves in the form of equations, requiring us to apply various mathematical concepts to arrive at a solution. This week, we are presented with a scenario involving distance, rate, and time, which we will use to explore the world of algebra and mathematical reasoning.
The Problem
Theo, a keen walker and jogger, has been keeping track of his activities this week. He walked for $x$ hours at a constant rate of 4 miles per hour and jogged $y$ hours at a constant rate of 6 miles per hour. The total distance he covered through walking and jogging is 36 miles. We are tasked with determining the values of $x$ and $y$ that satisfy this condition.
Mathematical Formulation
To approach this problem, we can use the formula for distance, which is given by:
In this scenario, we have two types of activities: walking and jogging. The distance covered through walking is given by:
Similarly, the distance covered through jogging is given by:
The total distance covered is the sum of the distances walked and jogged, which is given as 36 miles. Therefore, we can write the equation:
Solving the Equation
To solve for $x$ and $y$, we can use various algebraic techniques. One approach is to isolate one of the variables and then substitute it into the other equation. Let's isolate $x$ by subtracting $6y$ from both sides of the equation:
Dividing both sides by 4, we get:
Simplifying the expression, we get:
Substitution Method
Another approach to solving the equation is to use the substitution method. Let's substitute the expression for $x$ into the original equation:
Expanding the expression, we get:
Simplifying the equation, we get:
This equation is true for all values of $y$. Therefore, we can conclude that $y$ can take any value, and the corresponding value of $x$ will be given by:
Graphical Representation
To visualize the solution, we can plot the equation on a coordinate plane. Let's plot the equation $x = 9 - \frac{3}{2}y$ on a coordinate plane.
import matplotlib.pyplot as plt
import numpy as np

y = np.linspace(-10, 10, 400)
x = 9 - 1.5 * y
plt.plot(x, y)
plt.xlabel('x')
plt.ylabel('y')
plt.title('Graph of the Equation')
plt.grid(True)
plt.show()
Conclusion
In this article, we explored a mathematical problem involving distance, rate, and time. We used algebraic techniques to solve for the values of $x$ and $y$ that satisfy the given condition. We also used the substitution method to arrive at the solution and visualized the result using a graphical representation. This problem serves as a reminder of the importance of mathematical reasoning and problem-solving skills in real-world applications.
