A boxer needs to lose 3 kg in a month to be able to compete as a flyweight. In three weeks, he lowers 2 his weight from 55.5 kg to 53.8 kg. How many kilograms must the boxer lose in the final week to be able to compete as a flyweight?
The Correct Answer and Explanation is :
Answer:
The boxer must lose 0.7 kg in the final week to reach the required weight for the flyweight category.
Explanation:
- Understanding the Weight Loss Goal:
- The boxer starts with a weight of 55.5 kg.
- He needs to lose 3 kg in total.
- The target weight is:
[
55.5 \text{ kg} – 3 \text{ kg} = 52.5 \text{ kg}
]
- Weight Loss in the First Three Weeks:
- After three weeks, the boxer’s weight is 53.8 kg.
- Weight lost so far:
[
55.5 \text{ kg} – 53.8 \text{ kg} = 1.7 \text{ kg}
]
- Weight to Lose in the Final Week:
- To reach 52.5 kg, the remaining weight to lose is:
[
53.8 \text{ kg} – 52.5 \text{ kg} = 0.7 \text{ kg}
]
Additional Insights:
- The boxer has been losing weight at an average rate of:
[
\frac{1.7 \text{ kg}}{3 \text{ weeks}} \approx 0.5667 \text{ kg per week}
] - In the last week, he must lose 0.7 kg, which is slightly higher than his average weight loss rate so far.
- To achieve this, he may need to slightly adjust his training and diet.
