What is the calculated depth along a highway if the total length is 871,200 feet and divided by 660?

To determine the calculated depth along the highway, you need to divide the total length of the highway by 660. This calculation is performed with this formula:

Total Length of the Highway / Width/Depth Conversion Factor.

In this case, the total length is 871,200 feet, and you divide that by 660:

871,200 feet ÷ 660 = 1,320 feet.

This result gives us the calculated depth of 1,320 feet. Dividing by 660 is a common practice in highway construction or engineering to convert measurements based on a specific scale or regulation, often related to road dimensions or rights-of-way.

The other choices do not match this calculation and would not represent the correct depth based on the given length of the highway. Thus, 1,320 feet is the accurate answer that aligns with the mathematical division performed here.
