### Question

One way to measure the amount of energy that is expended during exercise is to use metabolic equivalents (MET). Here are some METS for various activities: Running 6 MPH: 10 METS

Sleeping: 1 MET

The number of calories burned per minute may be estimated using the following formula:

in kilograms

Write a program that calculates and outputs the total number of calories burned for a 150-pound person who runs 6 MPH for 30 minutes, plays basketball for 30 minutes, and then sleeps for 6 hours. One kilogram is equal to 2.2 pounds.

Program:

``````// CaloriesCalculator.java
public class CaloriesCalculator
{
public static final double KILOGRAMS_PER_POUND = 2.2;
public static final int RUNNING_METS = 10;
public static final int BASKETBALL_METS = 8;
public static final int SLEEPING_METS = 1;

public static void main(String[] args)
{
double weightInKilograms = 150 / KILOGRAMS_PER_POUND;
double runningTimeInMinutes = 30;
double sleepintTimeInMinutes = 6 * 60;

double caloriesBurnedForRunning = 0.0175
* RUNNING_METS * weightInKilograms
* runningTimeInMinutes;

double caloriesBurnedForSleeping = 0.0175
* SLEEPING_METS * weightInKilograms
* sleepintTimeInMinutes;

double totalCaloriesBurned = caloriesBurnedForRunning
+ caloriesBurnedForSleeping;

System.out.println(
"Number of calories burned for running:    "
+ caloriesBurnedForRunning);

System.out.println(
"Number of calories burned for basketball: "

System.out.println(
"Number of calories burned for sleeping:   "
+ caloriesBurnedForSleeping);

System.out.println(
"\nTotal number of calories burned per minute: "
+ totalCaloriesBurned);
}
}``````

Output:

``````Number of calories burned for running:    357.95454545454544
Number of calories burned for basketball: 286.3636363636364
Number of calories burned for sleeping:   429.5454545454545

Total number of calories burned per minute: 1073.8636363636363```

**Anne is using a calorie tracker app that helps her keep a record of all her physical activities and her daily intake of calories**

**The calories burned by her doing some of the common physical activities are:**

1. 30 minutes of cycling burns around 300 calories

2. 30 minutes of swimming burns around 200 calories

3. 30 minutes of running burns around 500 calories

**Anne can lose one pound of weight for each 1000 calories burned. Her daily extra calorie intake tracked by the app is 100**

**Write a java program to calculate the number of pounds Anne can lose in a month if she does each of the above mentioned activities

once a week for 1 hour and chooses to do one activity per day.**

**Sample Input:**

Calorie burnt by cycling : 200

Calorie burnt by running : 200

Calorie burnt by swimming: 200

Calorie intake in a day  : 100

**Sample Output:**

Weight lost by Anne in a month is : 5.0 pounds
