Chapter 1 Question 1.12, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

(Average speed in kilometers) Assume a runner runs 24 miles in 1 hour, 40 minutes, and 35 seconds. Write a program that displays the average speed in kilometers per hour. (Note that 1 mile is 1.6 kilometers.)

Solution

//Program - 12

public class HelloWorld

{

    public static void main(String[] args)

    {

       

        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);

    }

}

OUTPUT

 

Miles / (hour + (minutes / 60) + (seconds / 3600)) * 1.6

24    / (1    + (40      / 60) + (35      / 3600))  * 1.6
