**Distance Conversion and Time Calculation**

**Problem Statement:**

If you swam at a rate of 426.7 centimeters per second, how many hours would it take you to swim 15.1 miles?

**Solution Explanation:**

To solve this problem, follow these steps:

1. **Convert the distance from miles to centimeters:**
   - There are 160,934 centimeters in a mile.
   - Therefore, \( 15.1 \) miles is:
     \( 15.1 \, \text{miles} \times 160,934 \, \text{cm/mile} = 2,430,113.4 \, \text{cm} \).

2. **Calculate the total time it will take to swim the distance:**
   - Given the swimming speed is \( 426.7 \) cm per second, the time in seconds required to swim \( 2,430,113.4 \) cm is:
     \( \frac{2,430,113.4 \, \text{cm}}{426.7 \, \text{cm/second}} \approx 5697.37 \, \text{seconds} \).

3. **Convert the time from seconds to hours:**
   - There are \( 3600 \) seconds in an hour, so the time in hours is:
     \( \frac{5697.37 \, \text{seconds}}{3600 \, \text{seconds/hour}} \approx 1.58 \, \text{hours} \).

Therefore, it would take approximately \( 1.58 \) hours to swim \( 15.1 \) miles at a rate of \( 426.7 \) centimeters per second.
