Introduction

When working with different units of measurement, it's essential to understand how to convert between them. In this article, we'll focus on converting inches per minute to feet per minute. We'll explore the correct expression to use and provide a step-by-step guide to help you understand the process.

Understanding the Units

Before we dive into the conversion, let's understand the units involved:

Inches (in): A unit of length, equal to 1/12 of a foot.
Minutes (min): A unit of time, equal to 1/60 of an hour.
Feet (ft): A unit of length, equal to 12 inches.

The Correct Expression

To convert 100 inches per minute to feet per minute, we need to use the correct expression. Let's examine the options:

A. $\frac{100 \text{ inches}}{1 \text{ minute}} \times \frac{60 \text{ minutes}}{1 \text{ hour}}$

B. $\frac{100 \text{ inches}}{1 \text{ minute}} \times \frac{1 \text{ hour}}{60 \text{ minutes}}$

C. $\frac{100 \text{ inches}}{1 \text{ minute}} \times \frac{1 \text{ foot}}{12 \text{ inches}}$

Analyzing the Options

Let's analyze each option:

Option A: This expression is incorrect because it multiplies the number of minutes by 60, which is not necessary for the conversion.
Option B: This expression is also incorrect because it divides the number of hours by 60, which is not necessary for the conversion.
Option C: This expression is the correct one. It multiplies the number of inches by the conversion factor of 1 foot to 12 inches, which gives us the correct result in feet per minute.

Step-by-Step Guide

Now that we've identified the correct expression, let's walk through the step-by-step process:

Identify the units: We have 100 inches per minute and want to convert it to feet per minute.
Determine the conversion factor: We know that 1 foot is equal to 12 inches, so we can use this conversion factor to convert inches to feet.
Apply the conversion factor: Multiply the number of inches by the conversion factor: $\frac{100 \text{ inches}}{1 \text{ minute}} \times \frac{1 \text{ foot}}{12 \text{ inches}}$
Simplify the expression: Simplify the expression to get the final result in feet per minute.

Conclusion

Converting units of measurement requires a clear understanding of the units involved and the correct expression to use. In this article, we've explored the correct expression to convert 100 inches per minute to feet per minute. By following the step-by-step guide, you can confidently convert between different units of measurement.
