Question

A light should be located from _____ to _____ ft over the surface of a road, less than 40' wide, and from ______ to ______ ft on roads more than 40' wide.

a. 10 to 15, 20 to 25
b. 15 to 20, 25 to 30
c. 20 to 25, 30 to 35
d. 25 to 30, 35 to 40

Answer 1

Without information specific to roadway lighting standards, it is not possible to provide the correct height range for street lights over roads of different widths. The question seems to involve physics, particularly with regard to illumination and visibility, but more data is required to answer confidently.

Step-by-step explanation:

The question pertains to the optimal height for a street light over a roadway. The goal in determining this height is to ensure proper illumination of the road for visibility and safety purposes. For roads that are less than 40' wide, the ideal height would generally be lower than the height required for wider roads due to the lesser area that needs to be covered. The recommended heights are not presented in the reference information provided, so it's not possible to give a definitive answer based on the information available.
