In a particular jurisdiction, taxi fares consist of a base fare of $4.00, plus $0.25 for every 140 meters traveled. write a function that takes the distance traveled (in kilometers) as its only parameter and returns the total fare as its only result. write a main program that demonstrates the function.

// here is code in java.

import java.util.*;

// class definition

class Main

{

// method that return total fare

   public static double fare(double dis)

   {

   // calculate the total fare

       double tot_fare=(4+((dis*1000)/140)*0.25);

       return the fare

       return tot_fare;

   }

   //driver method

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // scanner object to read input string

       Scanner s=new Scanner(System.in);

        // variable

       double dis;

       System.out.print("please enter the distance in KM: ");

       //read the number

       dis=s.nextDouble();

       // call the function with "dis" parameter

     double ride_fare=fare(dis);

     // print the total fare

     System.out.println("total fare is: "+ride_fare);

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read the distance from user with the help of scanner class.Call the function with parameter "dis".Here it will calculate the total fare as (4+((dis*1000)/140)*0.25). Here base fare is $4 and $0.25 for every 140 meter.Then function will return the total fare.

Output:

please enter the distance in KM: 7                                                                                                                            

total fare is: 16.5
