Question

define 1mi, 1lb, 1c, 1 k in the international system (si)

\\(4\text{km}, 0.8\text{kg}, 3x10^3\text{m}, c + 300\\)
\\(24\text{km}, 4.5\text{kg}, 7x10^6\text{m}, c + 73.15\\)
\\(1.6\text{km}, 0.45\text{kg}, 3x10^8\text{m}, c + 273.15\\)

Explanation:

Convert mile to kilometers

$$ 1\text{ mi} \approx 1.609\text{ km} \approx 1.6\text{ km} $$

Convert pound to kilograms

$$ 1\text{ lb} \approx 0.4536\text{ kg} \approx 0.45\text{ kg} $$

Convert coulomb to SI base units and kelvin conversion

Answer:

• (A) \(4\text{km}, 0.8\text{kg}, 3\times10^3\text{ m}, \text{C} + 300\)
• (B) \(24\text{km}, 4.5\text{kg}, 7\times10^6\text{ m}, \text{C} + 73.15\)
• (C) \(1.6\text{km}, 0.45\text{kg}, 3\times10^9\text{ m}, \text{C} + 273.15\) (Correct answer)
