The maximum net quantity of dry ice allowed per package or per person is:
A. 2.3 lb, 1.01 kg
B. 2.0 kg, 4.4 lb
C. 2.5 kg, 5.5 lb
D. 2.0 lb, .98 kg
Answer (2)
Convert kilograms to pounds using the conversion factor 1 kg = 2.20462 lb .
Option 1: 1.01 kg ≈ 2.23 lb (given 2.3 lb ).
Option 2: 2.0 kg ≈ 4.41 lb (given 4.4 lb ).
Option 3: 2.5 kg ≈ 5.51 lb (given 5.5 lb ).
Option 4: 0.98 kg ≈ 2.16 lb (given 2.0 lb ).
The closest match is 2.0 kg , 4.4 lb .
Explanation
Problem Analysis We are given four options for the maximum net quantity of dry ice allowed per package or per person. Each option provides a weight in both pounds (lb) and kilograms (kg). Our goal is to determine which option provides the most accurate conversion between these two units of weight.
Conversion Strategy To solve this, we will use the conversion factor between kilograms and pounds, which is approximately 1 kg = 2.20462 lb . We will convert the kilograms to pounds for each option and see which one matches the given pounds value most closely.
Option 1 Conversion Option 1: 1.01 kg × 2.20462 kg lb = 2.2266662 lb . This is close to 2.3 lb .
Option 2 Conversion Option 2: 2.0 kg × 2.20462 kg lb = 4.40924 lb . This is very close to 4.4 lb .
Option 3 Conversion Option 3: 2.5 kg × 2.20462 kg lb = 5.51155 lb . This is very close to 5.5 lb .
Option 4 Conversion Option 4: 0.98 kg × 2.20462 kg lb = 2.1605276 lb . This is not very close to 2.0 lb .
Selecting the Best Option Comparing the results, Option 2 ( 2.0 kg = 4.4 lb ) and Option 3 ( 2.5 kg = 5.5 lb ) are the closest matches. However, since the question asks for the maximum net quantity, and Option 3 has slightly higher values, we choose Option 2 as it is a more precise match.
Final Answer Therefore, the maximum net quantity of dry ice allowed per package or per person is 2.0 kg , 4.4 lb .
Examples
Understanding unit conversions is crucial in many real-world scenarios, especially in fields like transportation and logistics. For instance, when shipping goods internationally, knowing the weight limits in both pounds and kilograms ensures compliance with regulations in different countries. This prevents delays and fines, making the shipping process smoother and more efficient. Also, consider a scenario where you are baking a cake using a recipe from another country. The recipe might list ingredients in grams, but your kitchen scale measures in ounces. Converting grams to ounces accurately ensures that you use the correct amount of each ingredient, leading to a perfectly baked cake.
The maximum net quantity of dry ice allowed per package or per person is Option B: 2.0 kg, 4.4 lb, which provides an accurate conversion between the units based on verified calculation. This shows that both values closely match according to the standard conversion factor of 1 kg = 2.20462 lb.
