CHALLENGE ACTIVITY
6.4.1: Functions: Factoring out a unit-conversion calculation.
 
Write a function so that the main program below can be replaced by the simpler code that calls function mph_and_minutes_to_miles(). Original main program:
miles_per_hour = float(input()) minutes_traveled = float(input()) hours_traveled = minutes_traveled / 60.0 miles_traveled = hours_traveled * miles_per_hour print('Miles: {:f}'.format(miles_traveled))


Sample output with inputs: 70.0 100.0
Miles: 116.666667
### Python Code for Calculating Miles Traveled This snippet of Python code is designed to calculate the number of miles traveled given a speed in miles per hour and the duration of travel in minutes. Below is a detailed explanation of the code structure and functionality: ```python ''' Your solution goes here ''' miles_per_hour = float(input()) minutes_traveled = float(input()) print('Miles: {:.f}'.format(mph_and_minutes_to_miles(miles_per_hour, minutes_traveled))) ``` #### Code Breakdown 1. **Comment Line:** - The first line is a comment placeholder (`''' Your solution goes here '''`), indicating where additional code can be added or explanations provided. Comments in Python are used to make the code more understandable to others. 2. **Variable Initialization:** - `miles_per_hour = float(input())`: - This line prompts the user to input the speed in miles per hour (`mph`). The input is then converted to a float to accommodate decimal values. - `minutes_traveled = float(input())`: - This line prompts the user to input the time traveled in minutes. Similarly, the input is converted to a float for precision. 3. **Output:** - The `print` function outputs the calculated miles traveled. The function `mph_and_minutes_to_miles(miles_per_hour, minutes_traveled)` is used to compute this value. - `'{:.f}'.format(...)` specifies the formatting of the output. However, the format specifier `:.f` seems to be incorrect and may cause an error; it should likely be `:f` to properly format the number of miles as a floating-point number. 4. **Function Placeholder:** - The function `mph_and_minutes_to_miles` is presumed to be defined elsewhere. This function likely contains the logic to convert the provided `miles_per_hour` and `minutes_traveled` into a distance traveled in miles. #### Usage - **Input:** The program asks for two inputs. - Speed in miles per hour. - Time traveled in minutes. - **Output:** The program will output the total miles traveled during this time at the given speed. This code could be used in educational contexts to demonstrate basic input handling, type conversion, and output formatting in Python. Note that the function required to complete this task (`mph_and_minutes_to_miles`) is not provided in the snippet
