Question

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.

Answer 1

import java.util.Scanner;

public class ANot {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.println("Please Enter the number of fuel gallons in the car's tank: ");

int numGallons = input.nextInt();

System.out.print("What is the fuel efficiency of your car in miles/gallon ");

double fuelEffi = input.nextDouble();

System.out.print("How much is the price per gallon: ");

double price = input.nextDouble();

double milesCanGo = fuelEffi*numGallons;

double numOfGallons100Miles = 100/fuelEffi;

System.out.println("The cost per 100 miles is "+numOfGallons100Miles*price);

System.out.println("Your car can go as far as "+milesCanGo+" miles with the current fuel " +

"in your tank");

}

}

Step-by-step explanation:

Using Java programming language;

1. Import the Scanner class to receive user input
2. Prompt user to input numofGallons, fuelEfficiency and pricePerGallon
3. Calculate the miles the car can go with the formula milesCanGo = numofGallons X fuelEfficiency
4. Calculate the number of gallons for 100 miles distance (100/fuelEfficiency)
5. The cost of driving 100 miles is (100/fuelEfficiency)*pricePerGallon
6. Output cost for 100 miles and how far the car can go.
