Question

Write a method so that the main() code below can be replaced by the simpler code that calls method mphandminutestomiles(). original main(): public class calcmiles { public static void main(string [] args) { double milesperhour = 70.0; double minutestraveled = 100.0; double hourstraveled; double milestraveled; hourstraveled = minutestraveled / 60.0; milestraveled = hourstraveled * milesperhour; system.out.println("miles: " + milestraveled); } }

Answer 1

int main(void)

{

  double milesPerHour = 70.0;

  double minutesTraveled = 100.0;

  double hoursTraveled;

  double milesTraveled;

  hoursTraveled = minutesTraveled / 60.0;

  milesTraveled = hoursTraveled * milesPerHour;

  printf("Miles: %lf\n", milesTraveled);

   return 0;

}

Answer 2

The simpler code for the given main () code 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:

Code:

import java.util.Scanner;

public class CalcMiles

{

/*Your solution starts here */

//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
