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. This conversion is crucial in various fields, such as engineering, physics, and everyday applications. We'll explore the correct expression to use for this conversion 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 in the imperial system, 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 in the imperial system, 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 provided:

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

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

Analyzing Option A

Option A involves multiplying the number of inches per minute by the number of minutes in an hour. However, this expression is incorrect because it doesn't account for the conversion from inches to feet.

Analyzing Option B

Option B involves multiplying the number of inches per minute by the conversion factor from inches to feet (1 foot / 12 inches). This expression is correct because it accurately converts the units from inches to feet.

Step-by-Step Conversion

Now that we've identified the correct expression, let's perform the conversion step by step:

Identify the conversion factor: The conversion factor from inches to feet is 1 foot / 12 inches.
Multiply the number of inches per minute by the conversion factor: Multiply 100 inches per minute by the conversion factor (1 foot / 12 inches).
Simplify the expression: Simplify the expression to obtain the final result in feet per minute.

Calculating the Result

Let's calculate the result using the correct expression:

$\frac{100 \text{ inches}}{1 \text{ minute}} \times \frac{1 \text{ foot}}{12 \text{ inches}} = \frac{100}{12} \text{ feet per minute}$

Conclusion

In conclusion, the correct expression to convert 100 inches per minute to feet per minute is:

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

This expression accurately converts the units from inches to feet, providing the correct result in feet per minute. By following the step-by-step guide and understanding the units involved, you can confidently perform this conversion in various applications.
