Write a program that declares constants to represent the number of inches, feet, and yards in a mile. Name the constants INCHES_IN_MILE, FEET_IN_MILE, and YARDS_IN_MILE respectively. Also declare a variable named miles to represent a number of miles. Compute and display, with explanatory text, the value in inches, feet, and yards—for example: 4.0 miles is 253440.0 inches, or 21120.0 feet, or 7040.0 yards.

This is what I have but it is only 50% correct:

import java. util. Scanner;
class MileConversions
{
public static void main(String[] args)
{
final double INCHES_IN_MILE = 63360.0;
final double FEET_IN_MILE = 5280.0;
final double YARDS_IN_MILE = 1760.0;
double miles = 4.0;

Scanner scanner = new Scanner(System. in);
System. out. print("Enter miles: ");
miles = scanner. nextDouble();

System. out. printf("%.1f miles is %.1f inches, or %.1f feet, or %.1f yards", miles, miles*INCHES_IN_MILE, miles*FEET_IN_MILE, miles*YARDS_IN_MILE);
