Nicolás is overweight and weighs 93 kg. His aim is to lose 400 g per week. If he manages to accomplish his weekly goal, how many weeks will it take for him to reach a mass of 82 kg?

Nicolás needs to lose 11,000 g to reach his target weight of 82 kg. At a rate of 400 g per week, it would take him 27.5 weeks. Since partial weeks aren't practical, this is rounded up to 28 weeks.

Explanation:

The student's question is a weight loss calculation problem in Mathematics, at a Middle School level. Nicolás weighs 93 kg and wants to reach 82 kg by losing 400 g per week. To find out how many weeks it will take Nicolás to reach his goal, we need to calculate the total weight loss required and then divide that by the weekly weight loss rate.

First, we calculate the total weight loss needed:
93 kg - 82 kg = 11 kg

Then, we convert 11 kg to grams because the weekly weight loss is given in grams:
11 kg = 11,000 g

Next, divide the total weight loss in grams by the weekly weight loss rate:
11,000 g ÷ 400 g/week = 27.5 weeks

Since Nicolás cannot lose weight for a fraction of a week, we'll round up the number of weeks to the nearest whole number. Therefore, it will take Nicolás 28 whole weeks to reach his goal of 82 kg.
