Write a program that asks the user to input
 • The number of gallons of gas in the tank
 • The fuel efficiency in miles per gallon
 • The price of gas per gallon
Then print the cost per 100 miles and how far the car can go with the gas in the tank.

Code:

import java.util.Scanner;

public class Main
{
        public static void main(String[] args) {
            
            Scanner input = new Scanner(System.in);
            double gas_tank;
            double fuel_efficiency;
            double gas_price;
            double cost_100_miles;
            double max_distance;
            
            System.out.print("Gas in tank: ");
            gas_tank = input.nextDouble();
            
            System.out.print("Fuel efficiency: ");
            fuel_efficiency = input.nextDouble();
            
            System.out.print("Price of gas: ");
            gas_price = input.nextDouble();
            
            input.close();
            
            cost_100_miles = 100 / fuel_efficiency * gas_price;
            System.out.printf("Cost per 100 miles: %.2f\n", cost_100_miles);
            max_distance = fuel_efficiency * gas_tank;
            System.out.println("Maximum distance: " + max_distance);
    }
}
