Misha Larkins [42]

The program is an illustration of a sequential structure

<h3>What are sequential control structures?</h3>

Sequential control structures are programs that do not require loops and conditional statements

<h3>The actual program</h3>

The program in Python where comments are used to explain each line, is as follows:

#This gets input for age

age = int(input("Age: "))

#This gets input for weight

weight = (input("Weight: "))

#This gets input for the heart rate

heartRate = float(input("Heart Rate: "))

#This gets input for the time

time = int(input("Time: "))

#This calculates the calories burnt

calories = ((age * 0.2757) + (weight * 0.03295) + (heartRate * 1.0781) - 75.4991 ) * time / 8.368

#This prints the calories burnt

print('calories: {:. 2f} calories'. Format(calories))
