Question

Using Java.

The distance a vehicle travels can be calculated as follows:
Distance = Speed * Time
For example, if a train travels 40 miles-per-hour for three hours, the distance traveled is 120 miles. Write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. Both values are assumed to be integers. It should use a
loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph for a three-hour time period, it should display a report similar to the one that follows:

Hours Distance Traveled
---------------------------
1 40
2 80
3 120

Do not accept a negative number for speed and do not accept any value less than 1 for time traveled.

Sample Run
java DistanceTravelled

Enter vehicle speed (in mph): 60?
Enter time travelled (in hrs): 2?
Hour?Distance Travelled?
--------------------------?
1??60?
2??120?

Solution

import java.util.*;
public class Main
{
        public static void main(String[] args) {
                Scanner sc=new Scanner(System.in);
                System.out.println("Enter vehicle speed (in mph)");
                int Speed=sc.nextInt();
                System.out.println("Enter time travelled (in hrs)");
                int Time=sc.nextInt();
                if(Speed<0 && Time<1){
                    
                    System.out.println("Please Enter Valid Speed and Time \n");
                }
                else{
                        System.out.println("Hour   Distance travelled");
                    for(int i=1;i<=Time;i++){
                       int Distance=Speed*i;
                       System.out.println(i+"         "+Distance);
