Answer :
The number of calories burned by a person weighing 143 lbs who jogs 1 mile in 8 minutes is approximately 92.95 calories, which corresponds with option B from the given selections.
To calculate the number of calories burned by a person weighing 143 lbs while jogging 1 mile in 8 minutes, we need to look at the general estimate for calories burned during this type of exercise. As mentioned in the reference material, running or jogging one mile burns almost 100 calories. However, this estimate is based on an average person's weight, which may not be specifically applicable to a person weighing 143 lbs.
Since the provided approximate values for calorie expenditure are given for a person weighing 154 lbs, we can use this information as a baseline and adjust it for a person weighing 143 lbs.
Using a simple ratio, we calculate: (Calories burned by 154 lb person) / 154 = (Calories burned by 143 lb person) / 143
Given the reference states that a 154 lb person burns approximately 370 calories per hour while jogging, we can set up the following equation:
370 / 154 = x / 143
Solving for x gives us the number of calories burned per hour by a 143 lb person. We then multiply this by (1/60) * 8 to find the calories burned in 8 minutes.
Thus, the correct factor chosen from the presentation is option B, 92.95 calories, as this correctly accounts for the weight and time while jogging.
The number of calories used per mile of jogging is determined both b an individual's weight and speed of running. Individuals of the same approximate weight running 6 mph or 1 mile every ten minutes have a calorie factor of 62% of their weight; i.e., calories burned= (weight)(0.62). If they run an 8 minute mile the factor is 65%.
(65*143) then divide by 100= 92.95 meaning your answer is B
(65*143) then divide by 100= 92.95 meaning your answer is B
