How many kilometers are in one mile?

• A. 0.914 kilometers
• B. 2.59 kilometers
• C. 3.785 kilometers
• D. 1.61 kilometers

Answer: (D)

Understanding how miles convert to kilometers relies on the conversion factor: 1 mile is about 1.609 kilometers. So one mile equals 1.609 kilometers, which rounds to 1.61 kilometers when given to two decimal places. That’s why 1.61 kilometers is the best answer — it matches the standard distance you get when converting miles to kilometers.

The other numbers don’t fit. 0.914 kilometers is only about 0.568 miles, not one mile. 2.59 kilometers is the amount of kilometers that would correspond to about 1.609 miles, which is the inverse direction of the conversion. And 3.785 kilometers isn’t a standard mile-to-kilometer conversion; it’s a distractor from a different common conversion.
