Jaimie's Running Journey Calculating Total Distance

Introduction: Unveiling Jaimie's Running Feats

In this article, we embark on a mathematical journey to unravel the distance Jaimie covered during her runs on Monday and Tuesday. Jaimie, an avid runner, clocked an impressive $3 \frac{1}{2}$ miles on Monday. On Tuesday, she decided to take it a bit easier, running half the distance she conquered on Monday. Our mission is to calculate the total distance Jaimie ran over these two days. This seemingly simple problem allows us to delve into the realms of fractions, mixed numbers, and basic arithmetic, providing a practical application of these concepts. Let's lace up our mathematical shoes and dive into the solution!

Monday's Run: Conquering $3 \frac{1}{2}$ Miles

On Monday, Jaimie showcased her running prowess by completing a noteworthy $3 \frac{1}{2}$ miles. To effectively work with this distance, we need to convert the mixed number into an improper fraction. This involves multiplying the whole number (3) by the denominator (2) and then adding the numerator (1), all while retaining the original denominator. Mathematically, this translates to: $3 \frac{1}{2} = \frac{(3 \times 2) + 1}{2} = \frac{7}{2}$ miles. Therefore, Jaimie ran $\frac{7}{2}$ miles on Monday. This conversion is crucial for simplifying subsequent calculations, especially when dealing with fractions and multiplication. Understanding how to convert mixed numbers to improper fractions is a fundamental skill in mathematics, allowing for seamless manipulation of these numbers in various operations.

Tuesday's Run: Half the Distance, Half the Effort?

Tuesday's run was a different story. Jaimie opted for a more relaxed pace, running only half the distance she ran on Monday. This introduces the concept of multiplying a fraction by a fraction. To determine the distance Jaimie ran on Tuesday, we need to multiply Monday's distance ($\frac{7}{2}$ miles) by $\frac{1}{2}$. The multiplication of fractions involves multiplying the numerators together and the denominators together. Thus, Tuesday's distance is calculated as: $\frac{1}{2} \times \frac{7}{2} = \frac{1 \times 7}{2 \times 2} = \frac{7}{4}$ miles. This result, $\frac{7}{4}$ miles, represents the distance Jaimie ran on Tuesday. We can also express this improper fraction as a mixed number, which is $1 \frac{3}{4}$ miles, providing a more intuitive understanding of the distance. Jaimie ran 1 and 3/4 miles on Tuesday, half the distance of Monday's run. This highlights the relationship between fractions and their practical application in real-world scenarios.

Calculating the Total Distance: Combining Monday and Tuesday's Efforts

To find the total distance Jaimie ran on Monday and Tuesday, we need to sum the distances she covered on each day. This involves adding the fraction representing Monday's distance ($\frac{7}{2}$ miles) to the fraction representing Tuesday's distance ($\frac{7}{4}$ miles). However, before we can add fractions, they must have a common denominator. In this case, the least common denominator (LCD) of 2 and 4 is 4. To express $\frac{7}{2}$ with a denominator of 4, we multiply both the numerator and denominator by 2, resulting in $\frac{14}{4}$. Now, we can add the fractions: $\frac{14}{4} + \frac{7}{4} = \frac{14 + 7}{4} = \frac{21}{4}$ miles. This sum, $\frac{21}{4}$ miles, represents the total distance Jaimie ran. To gain a clearer understanding of this distance, we can convert this improper fraction back into a mixed number. Dividing 21 by 4, we get a quotient of 5 and a remainder of 1. Thus, $\frac{21}{4}$ is equivalent to $5 \frac{1}{4}$ miles. Therefore, the combined distance of Jaimie's runs on Monday and Tuesday amounts to 5 and 1/4 miles. This calculation demonstrates the importance of understanding fraction addition and the conversion between improper fractions and mixed numbers in solving practical problems.

The Final Verdict: Jaimie's Total Mileage

In conclusion, Jaimie ran a total of $5 \frac{1}{4}$ miles on Monday and Tuesday. This was determined by first calculating the distance she ran on Tuesday, which was half of her Monday's distance, and then adding the two distances together. This problem showcased the application of fundamental mathematical concepts such as fraction manipulation, mixed number conversion, and addition of fractions. The journey of calculating Jaimie's total mileage serves as a testament to the practical relevance of these mathematical skills in everyday scenarios. By breaking down the problem into smaller, manageable steps, we were able to arrive at the solution, highlighting the power of structured problem-solving in mathematics.

Breaking Down the Problem: A Step-by-Step Approach

Let's revisit the steps we took to solve this problem, reinforcing the underlying mathematical principles:

1. Converting the Mixed Number to an Improper Fraction: We transformed Monday's distance, $3 \frac{1}{2}$ miles, into an improper fraction, $\frac{7}{2}$ miles. This conversion is essential for simplifying multiplication and addition operations involving mixed numbers.
2. Calculating Tuesday's Distance: We determined that Jaimie ran half the distance on Tuesday, which involved multiplying Monday's distance ($\frac{7}{2}$ miles) by $\frac{1}{2}$, resulting in $\frac{7}{4}$ miles. This step highlights the concept of multiplying fractions and its application in finding a fraction of a quantity.
3. Finding a Common Denominator: To add Monday's and Tuesday's distances, we needed a common denominator. The least common denominator of 2 and 4 is 4. We converted $\frac{7}{2}$ to $\frac{14}{4}$ to facilitate addition.
4. Adding the Fractions: We added the fractions $\frac{14}{4}$ and $\frac{7}{4}$ to find the total distance, resulting in $\frac{21}{4}$ miles.
5. Converting the Improper Fraction to a Mixed Number: Finally, we converted the improper fraction $\frac{21}{4}$ back into a mixed number, $5 \frac{1}{4}$ miles, to provide a more intuitive representation of the total distance.

This step-by-step approach demonstrates how complex problems can be solved by breaking them down into smaller, more manageable steps. Each step utilizes fundamental mathematical principles, reinforcing the importance of mastering these concepts for effective problem-solving.
