Java Arithmetic Operator calculate average speed in kilometers

Question

Assume a runner runs 24 miles in 1 hour, 40 ?minutes, and 35 seconds.

We would like to write a program that displays the average speed in kilometers per hour.

1 mile is 1.6 kilometers.

Code structure you can use: 

public class Main {
  public static void main(String[] agrs) {
       //your code here
  }
}



public class Main {
  public static void main(String[] agrs) {
    System.out.println("Miles / (hour + (minutes / 60) + (seconds / 3600)) * 1.6");
    System.out.println("24    / (1    + (40      / 60) + (35      / 3600))  * 1.6");
    System.out.println((24 / (1 + (40 / 60.0) + (35 / 3600.0))) * 1.6);
  }
}

Note

The following code creates method to clear the calculation steps. 

public class Main {
  public static void main(String[] args) {
    System.out.println("kph: " + mphToKph(milesPerHour(24, 100.58)));
  }//from  w  ww  . j a  va2s  .  c om

  private static double milesPerHour(double miles, double minutes) {
    return 60.0 * (miles / minutes);
  }

  private static double mphToKph(double mph) {
    return mph * 1.6;
  }
}
