The answer is: B. Lose 10 pounds in three months.
BMI is calculated with this formula:
[tex]\frac{Weight in Kilograms}{height-in-meter^{2} }[/tex]
This mean that for a 1. 65 meter (5'5'') tall student to obtain a BMI of 28, the weight must be
weight = BMI x 1.65^2
weight = 28 x 2.7225
weight = 76.23 kilograms.
Normal BMI range is 18 - 25
To reach a BMI of 25, the student's weight must be
'weight = 25 x 1.65^2
weight = 68 kilograms
Total weight that the student need to lose
= 76.23 kg - 68 kg
= 8.23 kg or 18.14 pound
Healthy amount of weight to lose is around 1 pounds per week. So, the student need around 18 weeks to lose all the weight.
Because of this, losing 10 pound in three months (12 weeks) is a good benchmark since it provide realistic timing and expectation for the student.
Answer:
The answer is B, lose 10 pounds in 3.
Explanation:
Losing weight isn't easy and to be reasonable, faster isn't always better in that matter. Losing 10 pounds in 6 months is under achieving, losing 60 in six months is unreasonable, and losing 20 in six is underachieving as well. So, the answer is B.
