Introduction

In this article, we will delve into a fascinating mathematical problem involving two bugs running along a rectangular frame. The problem is as follows: two bugs start from the same corner, one running east and the other running south. The bug running east is 2 inches per second faster than the bug running south. After one second, neither bug has turned a corner, and the distance between them is 10 inches. Our goal is to find the speed of each bug.

The Problem Statement

Let's break down the problem statement:

Two bugs start from the same corner of a rectangular frame.
The bug running east is 2 inches per second faster than the bug running south.
After one second, the distance between the two bugs is 10 inches.
Neither bug has turned a corner after one second.

Mathematical Formulation

To solve this problem, we need to use the concept of distance, speed, and time. Let's denote the speed of the bug running south as x inches per second. Then, the speed of the bug running east is x + 2 inches per second.

Since the bugs are running along the sides of the rectangular frame, we can assume that the frame has a length of l inches and a width of w inches. The bug running south will cover a distance of x inches in one second, while the bug running east will cover a distance of (x + 2) inches in one second.

The Distance Between the Bugs

After one second, the distance between the two bugs is 10 inches. We can use the Pythagorean theorem to relate the distances covered by the bugs to the distance between them:

√((x + 2)^2 + x^2) = 10

Simplifying the Equation

We can simplify the equation by squaring both sides:

(x + 2)^2 + x^2 = 100

Expanding the left-hand side, we get:

x^2 + 4x + 4 + x^2 = 100

Combine like terms:

2x^2 + 4x - 96 = 0

Solving the Quadratic Equation

We can solve the quadratic equation using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 2, b = 4, and c = -96. Plugging in these values, we get:

x = (-4 ± √(16 + 768)) / 4

x = (-4 ± √784) / 4

x = (-4 ± 28) / 4

We have two possible solutions for x:

x = (-4 + 28) / 4 = 6

x = (-4 - 28) / 4 = -8

Since the speed of the bug cannot be negative, we discard the solution x = -8.

Finding the Speed of the Bug Running East

Now that we have found the speed of the bug running south (x = 6 inches per second), we can find the speed of the bug running east:

Speed of bug running east = x + 2 = 6 + 2 = 8 inches per second

Conclusion

In this article, we have solved a fascinating mathematical problem involving two bugs running along a rectangular frame. We have found the speed of each bug, which is 6 inches per second for the bug running south and 8 inches per second for the bug running east.
