If a mile is approximately equal to how many kilometers?

1. 1.6 km

2. 2.0 km

3. 0.8 km

4. 3.0 km

The correct answer is: 1.6 km

The conversion factor between miles and kilometers indicates that 1 mile is approximately equal to 1.6 kilometers. This relationship is based on the definition of both units of measurement, where 1 mile is defined as being equivalent to about 1.60934 kilometers. In practical terms, this means that when you have a distance in miles and you want to convert it to kilometers for more universal comprehension, you multiply the number of miles by this conversion factor, resulting in a quantity close to 1.6 times the number of miles. For instance, if you were to convert 5 miles into kilometers using this factor, you would calculate 5 miles x 1.6 km/mile, resulting in 8 kilometers. This conversion is widely used in contexts where metric measurements are more common, and understanding this relationship is essential for anyone working with distances in different systems of measurement. Hence, 1 mile being approximately equal to 1.6 kilometers is a well-established fact that reflects the conversion rate accurately.
