Final answer:
The road is approximately 16.09 kilometers long.
Step-by-step explanation:
To convert miles to kilometers, we can use the conversion factor that 1 mile is approximately equal to 1.609 kilometers.
So if a road measures 10 miles in length, we can multiply 10 by 1.609 to find the length in kilometers.
10 miles * 1.609 km/mile = 16.09 kilometers
Therefore, the road is approximately 16.09 kilometers long.
