Write a program that takes the distance of the commute in kilometres, the car fuel consumption rate in kilometre per gallon, and the price of a gallon of petrol as input. The program should then display the cost of the commute.

Java

import java.util.Scanner;
 
public class CommuteCostCalculator {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
 
        // Input values
        System.out.print("Enter distance of commute (in km): ");
        double distance = sc.nextDouble();
 
        System.out.print("Enter car fuel consumption (km per gallon): ");
        double mileage = sc.nextDouble();
 
        System.out.print("Enter price of petrol per gallon: ");
        double pricePerGallon = sc.nextDouble();
 
        // Calculations
        double gallonsRequired = distance / mileage;
        double totalCost = gallonsRequired * pricePerGallon;
 
        // Output
        System.out.println("\nCost of the commute = Rs. " + totalCost);
 
        sc.close();
    }
}

Output

 
SAMPLE INPUT : 
Enter distance of commute (in km): 40
Enter car fuel consumption (km per gallon): 20
Enter price of petrol per gallon: 350

SAMPLE OUTPUT : 
Cost of the commute = Rs. 700.0
