Question

in .java

Write a program that computes the time to arrive to destination. It asks for the distance and the car speed. It will assume that the car travels at constant speed at all time.
Sample run 1:

This program will compute the travel time.
Enter the distance (miles): 105
Enter the car speed (miles/hour): 75
Travel time: 1.40
or: 1 hour and 23 minutes

Sample run 2:

This program will compute the travel time.
Enter the distance (miles): 150
Enter the car speed (miles/hour): 60
Travel time: 2.50
or: 2 hour and 30 minutes

Answer 1

import java.util.Scanner;

public class DistanceTravelled {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.println("This program will compute the travel time.");
        System.out.print("Enter the distance (miles): ");
        double distance = in.nextDouble();
        System.out.print("Enter the car speed (miles/hour): ");
        double speed = in.nextDouble();
        double time = distance / speed;
        System.out.printf("Travel time: %.2f\n", time);
        int hours = (int) time;
        int minutes = (int) ((time - hours) * 60);
        System.out.println("or: " + hours + " hour and " + minutes + " minutes");
    }
}
