Float, speed units C# Exercise - C# Programming Course

using System;  // Import the System namespace to use basic classes like Console

class Program  // Define the main class of the program

    static void Main()  // The entry point of the program
    {
        // Ask the user for the distance in meters
        Console.Write("Enter the distance in meters: ");  // Display prompt for distance
        float distance = float.Parse(Console.ReadLine());  // Read and parse the user's input for distance

        // Ask the user for the time in hours, minutes, and seconds
        Console.Write("Enter the time in hours: ");  // Prompt for hours
        int hours = int.Parse(Console.ReadLine());  // Read and parse the hours

        Console.Write("Enter the time in minutes: ");  // Prompt for minutes
        int minutes = int.Parse(Console.ReadLine());  // Read and parse the minutes

        Console.Write("Enter the time in seconds: ");  // Prompt for seconds
        int seconds = int.Parse(Console.ReadLine());  // Read and parse the seconds

        // Calculate the total time in seconds
        int totalTimeInSeconds = (hours * 3600) + (minutes * 60) + seconds;  // Convert hours and minutes to seconds and add the seconds

        // Calculate speed in meters per second
        float speedInMetersPerSecond = distance / totalTimeInSeconds;  // Speed = distance / time

        // Calculate speed in kilometers per hour
        float speedInKilometersPerHour = (distance / 1000) / (totalTimeInSeconds / 3600f);  // Speed in km/h = (distance in meters / 1000) / (time in seconds / 3600)

        // Calculate speed in miles per hour
        float speedInMilesPerHour = (distance / 1609) / (totalTimeInSeconds / 3600f);  // Speed in mph = (distance in meters / 1609) / (time in seconds / 3600)

        // Display the calculated speeds
        Console.WriteLine($"Speed in meters per second: {speedInMetersPerSecond:F2} m/s");  // Display speed in meters per second, formatted to 2 decimal places
        Console.WriteLine($"Speed in kilometers per hour: {speedInKilometersPerHour:F2} km/h");  // Display speed in km/h, formatted to 2 decimal places
        Console.WriteLine($"Speed in miles per hour: {speedInMilesPerHour:F2} mph");  // Display speed in mph, formatted to 2 decimal places
