Question

Write a method so that the main() code below can be replaced by the simpler code that calls method mphandminutestomiles(). original main():

Answer 1

Create the function as a double. Put both your variables to call inside the () of the created function. Then create a variable to hold the answer. 

double MphAndMinutesToMiles(double milesPerHour, double minutesTraveled){ double miles;  miles = (minutesTraveled / 60) * milesPerHour;  return miles;}

Answer 2

The simpler code for the given main ( ) function is shown below. For this, calculate the hours and miles before the main function and store them in the separate variables and after this, use these variables in main ( ) code. The below complete code is written in Java which  reduce the given main ( ) code and also make it simple.

Further Explaination:

The simple code in Java to calculate the miles traveled is shown below:

Code: Simple.java

import java.util.Scanner;

public class CalcMiles

{

//Define the method calcMilesTraveled().

Public double calcMilesTraveled (double mph, double minutesTravelled)

{

//Declare required variables.

Double hoursTravelled = 0.0;

Double milesTravelled = 0.0;

//Calculate the hours travelled and miles travelled.

hoursTravelled = minutesTravelled / 60.0;

milesTravelled = hoursTravelled * mph;

//The total miles travelled in return.

Return milesTravelled;

}

public static void main(String [] args)

{

double milesPerHour = 70.0;

double minsTravelled = 100.0;

CalcMiles tripCalculator = new CalcMiles();

System.out.println("Miles: " + tripCalculator.calcMilesTraveled (milesPerHour, minsTraveled));

}

}

Output:

Run the program, the output will be look like as below:

Miles: 116.66666666666667
