Homework Help: Questions and Answers: The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journal article (source):

Calories= (Age x 0.2757+ Weight 0.03295 + Heart Rate × 1.0781-75.4991) × (Time)/8.368

Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output the average calories burned for a person.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
print (f’ Calories: {calories:.2f} calories’)
Ex: If the input is: 49 155 148 60
then the output is:
Calories: 736.21 calories

Answer:

To solve the problem step by step, let’s break it down. The task is to compute the average calories burned based on the provided formula:

Calories = ((Age×0.2757) + (Weight×0.03295) + (HeartRate×1.0781) − 75.4991) × (Time/8.368)

Steps:

• Input: Get inputs for age, weight, heart rate, and time.
• Apply Formula: Plug these values into the formula to calculate the calories burned.
• Formatting: Ensure the output is displayed with two decimal places.

Python Code:

# Get user inputs
age = int(input())
weight = float(input())
heart_rate = float(input())
time = float(input())
# Calculate calories using the given formula
calories = ((age * 0.2757) + (weight * 0.03295) + (heart_rate * 1.0781) - 75.4991) * (time / 8.368)
# Output the result formatted to two decimal places
print(f'Calories: {calories:.2f} calories')

Example:

Input:

49 155 148 60

Output:

Calories: 736.21 calories

Explanation:

• Age: 49
• Weight: 155 pounds
• Heart Rate: 148 bpm
• Time: 60 minutes

The formula is applied as:

Calories = ((49×0.2757) + (155×0.03295) + (148×1.0781) − 75.4991) × (608.368)

This results in approximately 736.21 calories.
