1. Tienes 5400 pulgadas de rollitos de fruta. Quieres empaquetarlos para venderlos; para ello, debes convertir las pulgadas a centímetros.

3. Son 54 millas hasta Fayetteville. ¿Cuántos kilómetros son esto?

Sure! Let's go through the questions step-by-step and provide detailed solutions:

### 1. Convert 5400 inches to centimeters

To convert inches to centimeters, we use the conversion factor that 1 inch equals 2.54 centimeters. Here's how the calculation works:

- Inches: 5400
- Conversion Factor: 1 inch = 2.54 cm

Now, multiply the number of inches by the conversion factor:

[tex]\[
5400 \text{ inches} \times 2.54 \text{ cm/inch} = 13716 \text{ cm}
\][/tex]

So, 5400 inches is equal to 13,716 centimeters.

### 2. Calculate the number of working weeks in 172 days

The school year has 172 working days, and we're considering a working week to only consist of Monday to Friday, which is 5 days.

- Total Working Days: 172
- Days per Week: 5

To find the number of working weeks, divide the total number of working days by the number of days in a working week:

[tex]\[
\frac{172 \text{ days}}{5 \text{ days/week}} = 34.4 \text{ weeks}
\][/tex]

Therefore, there are 34.4 working weeks in 172 working days.

### 3. Convert 54 miles to kilometers

To convert miles to kilometers, we use the conversion factor that 1 mile equals approximately 1.60934 kilometers. Here's how the calculation works:

- Miles: 54
- Conversion Factor: 1 mile = 1.60934 km

Now, multiply the number of miles by the conversion factor:

[tex]\[
54 \text{ miles} \times 1.60934 \text{ km/mile} = 86.90436 \text{ km}
\][/tex]

So, 54 miles is equal to approximately 86.90436 kilometers.
