Question

luke is 5 feet 11 inches and weighs 170 pounds. using the body mass index chart as a guide, under which category would he fall? a underweight b normal c overweight d obese please select the best answer from the choices provided.

Explanation:

Step1: Convert height to inches

1 foot = 12 inches, so 5 feet 11 inches = 5×12 + 11 = 71 inches.

Step2: Calculate BMI (Body - Mass Index) formula in US units

BMI=$\frac{703\times weight (lbs)}{height (inches)^2}$. Substitute weight = 170 lbs and height = 71 inches. So, BMI=$\frac{703\times170}{71^2}=\frac{119510}{5041}\approx23.7$.

Step3: Determine BMI category

A normal BMI range is typically 18.5 - 24.9. Since 23.7 is in this range, Luke is in the normal - weight category.

Answer:

B. normal
