Question

in java

A way to measure the amount of energy spent during an exercise is to use metabolic

equivalents (MET). The formula to use is: METs x 3.5 x (weight in kg ) / 200 = calories burned per

minute .

For example, say you weigh 160 pounds (approximately 73 kg) and you play singles tennis,

which has a MET value of 8.

The formula would work as follows: 8 x 3.5 x 73 / 200 = 10.2 calories per minute. If you play

tennis for an hour, you’ll burn about 613 calories. Below are some METS for various activities:

● Running 6 MPH: 10 METS

● Tennis: 8 MEST

● Sleeping: 1 MET

Write a program that accepts an integer the weight of a person and calculates the total number

of calories the person burned while running 6 MPH for 30 minutes, playing tennis for 30

minutes, and sleeping for 9 hours.

Your program should output a single number rounded to an integer.

The table below illustrates output format samples (calculations may not be correct). Here ◦ is

a space and ↵ is a new line character. Your output should look exactly like on the samples

below with any number entered as a weight. Different wording, extra “spaces”, extra “lines”

are graded by the system as a “Wrong-Answer”. Make sure you follow the format.

Answer 1

import java.util.*;

class Main {
        public static void main(String[] args) {
                
                Scanner input = new Scanner(System.in);
                
                System.out.print("Input person's weight in kg: ");
                //Reading weight and converting it into KG by multiplying 0.45359237 to it
                double weight = 0.45359237*input.nextDouble();
                // precompute the temp value
                double temp = (3.5*weight)/200;
                //result 
                double result = temp*10*30 + temp*30*8 + temp*9*60*1;
                // rounded result
                int final_result = (int)result;
                // Printing the result
                System.out.print(final_result);
                
        }
}

OUTPUT:
