A 154-lb person burns 420 calories per hour riding an exercise bicycle at a rate of 15 mi/hr. Write a function rule to represent the total calories burned over time by that person. Explain how the information in the problem relates to the function.

The function rule to represent the total calories burned by the person over time can be written as:

C(t) = 420t

where C(t) represents the total calories burned after t hours of riding the exercise bicycle.

The given information in the problem includes the weight of the person (154 lbs), the rate of riding the exercise bicycle (15 mi/hr), and the calories burned per hour (420 calories/hr).

To understand how this information relates to the function rule, we need to use the following formula:

Calories Burned = (MET x weight in kg x time in hours)

where MET (Metabolic Equivalent of Task) is a measure of the energy expended during physical activities.

For riding an exercise bicycle at a rate of 15 mi/hr, the MET value is 8.5.

So, using the formula, we have:

Calories Burned = (8.5 x weight in kg x time in hours)

Since the weight of the person is given in pounds, we need to convert it to kilograms:

Weight in kg = Weight in lbs / 2.205

Weight in kg = 154 / 2.205

Weight in kg = 69.9

Now, substituting the values in the formula, we get:

Calories Burned = (8.5 x 69.9 x time in hours)

Calories Burned = 594.15 x time in hours

So, the function rule that we obtained earlier (C(t) = 420t) represents the total calories burned by the person over time, which is equivalent to the formula we derived (Calories Burned = 594.15 x time in hours). Both these expressions take into account the weight of the person, the rate of riding the exercise bicycle, and the time spent riding it, to calculate the total calories burned.

The function rule to represent the total calories burned over time by a person riding an exercise bicycle is C(t) = 420t, where C(t) is the number of calories burned after t hours of riding. The given information includes the person's weight (154 lbs), exercise bicycle riding rate (15 mi/hr), and calories burned per hour (420 calories/hr). Using the formula Calories Burned = (MET x weight in kg x time in hours), which considers the MET value as a measure of energy expended during physical activities, we find the MET for exercise bicycle riding at a rate of 15 mi/hr is 8.5. The weight of the person is then converted to kilograms (69.9 kg). Plugging the values into the formula, we get Calories Burned = 8.5 x 69.9 x time in hours, which simplifies to Calories Burned = 594.15 x time in hours. This expression is equivalent to the original function rule as both accounts for the person's weight, exercise bicycle riding rate, and time spent riding to calculate the total calories burned.

C(t) = 420t represents the function rule for calculating total calories burned by a person riding an exercise bicycle for t hours. The given information includes their weight (154 lbs), exercise bicycle riding rate (15 mi/hr), and calories burned per hour (420 cal/hr). Using the formula Calories Burned = (MET x weight in kg x time in hours), with the MET value for 15 mi/hr being 8.5, weight is converted to kilograms (69.9 kg) and values are plugged to get Calories Burned = 8.5 x 69.9 x time in hours, which is equivalent to the original function C(t) = 420t. Both formulas take the person's weight, exercise bicycle riding rate, and time spent riding into account to calculate total calories burned.

C(t) = 420t calculates calories for a person riding an exercise bike. We're given their weight, riding rate, and calories burned per hour. Using Calories Burned = (MET x weight in kg x time in hours) with a MET of 8.5 and 69.9 kg weight, we get an equivalent formula of Calories Burned = 8.5 x 69.9 x time in hours. Both formulas consider weight, riding rate, and time spent riding.
