question 6

convert the metric unit of length using unit ratios.
\\(5,710\text{ m} = \text{_______ km}\\)

• 57.1 km
• 57,100 km
• 5.71 km
• 571 km

Explanation:

State the conversion factor

$$ 1\text{ km} = 1,000\text{ m} $$

Apply the unit ratio

$$ 5,710\text{ m} \times \frac{1\text{ km}}{1,000\text{ m}} = \frac{5,710}{1,000}\text{ km} $$

Calculate the final value

$$ \frac{5,710}{1,000} = 5.71\text{ km} $$

Answer:

• 57.1 km
• 57,100 km
• 5.71 km (Correct answer)
• 571 km
