Introduction

Porter, a dedicated athlete, is part of the swim team and engages in rigorous training sessions that include both swimming and running. As part of his training regimen, Porter checks his heart rate halfway through his session to monitor his physical condition. In this article, we will focus on calculating Porter's heart rate when he runs, using a mathematical approach.

Understanding the Problem

Porter's heart rate is given in a table, but we need to calculate it when he runs. To do this, we need to understand the mathematical operation involved in the given table. The table shows a division operation, where 42 is divided by a fraction, 1/4.

Calculating the Heart Rate

To calculate Porter's heart rate, we need to evaluate the expression 42 divided by 1/4. This can be done using the following steps:

Invert and Multiply: When dividing by a fraction, we can invert the fraction and multiply instead. In this case, we will invert 1/4 to get 4/1.
Multiply: Now, we will multiply 42 by 4/1.

42 \times \frac{4}{1} = 42 \times 4 = 168

Conclusion

In conclusion, Porter's heart rate when he runs is 168. This calculation demonstrates the importance of understanding mathematical operations and applying them to real-world problems.

Discussion

This problem requires a basic understanding of mathematical operations, specifically division and inversion. The use of fractions and decimals is also essential in this calculation. By applying these mathematical concepts, we can accurately calculate Porter's heart rate when he runs.

Additional Tips and Variations

When working with fractions, it's essential to remember that dividing by a fraction is the same as multiplying by its reciprocal.
In this problem, we used the concept of inverting and multiplying to simplify the calculation. This technique can be applied to various mathematical problems involving fractions and decimals.
To make this problem more challenging, we can introduce additional variables or operations, such as adding or subtracting fractions.

Real-World Applications

This problem has real-world applications in various fields, including:

Sports: Athletes like Porter use heart rate monitoring to optimize their training sessions and improve their performance.
Medicine: Medical professionals use heart rate monitoring to diagnose and treat various medical conditions.
Science: Scientists use heart rate monitoring to study the effects of exercise on the human body.
