Final answer:
The question asks for the minimum taxi strip required for a vehicle to make a 180° turn with a 3-foot margin of safety. However, insufficient information is provided to answer this question correctly, as details such as the vehicle's turning radius are missing.
Step-by-step explanation:
The question pertains to a mathematical problem that involves determining the minimum turning space for a vehicle. The provided choices a) 37 feet b) 40 feet c) 45 feet, and d) 50 feet represent different potential minimum distances for a taxi strip for a 180° turn with an added margin of safety of 3 feet. This type of question is often related to geometry and space calculation, which falls under the subject of Mathematics.
However, without the necessary information such as the turning radius of the vehicle or any additional context, it is not possible to accurately determine the minimum taxi strip required for a 180° turn. Therefore, the question cannot be answered correctly in its current form.
